+Changelog for restic 0.8.1 (2017-12-27)
+=======================================
+
+The following sections list the changes in restic 0.8.1 relevant to
+restic users. The changes are ordered by importance.
+
+Summary
+-------
+
+ * Fix #1457: Improve s3 backend with DigitalOcean Spaces
+ * Fix #1454: Correct cache dir location for Windows and Darwin
+ * Fix #1459: Disable handling SIGPIPE
+ * Chg #1452: Do not save atime by default
+ * Enh #1436: Add code to detect old cache directories
+ * Enh #1439: Improve cancellation logic
+ * Enh #11: Add the `diff` command
+
+Details
+-------
+
+ * Bugfix #1457: Improve s3 backend with DigitalOcean Spaces
+
+   https://github.com/restic/restic/issues/1457
+   https://github.com/restic/restic/pull/1459
+
+ * Bugfix #1454: Correct cache dir location for Windows and Darwin
+
+   The cache directory on Windows and Darwin was not correct, instead the directory `.cache` was
+   used.
+
+   https://github.com/restic/restic/pull/1454
+
+ * Bugfix #1459: Disable handling SIGPIPE
+
+   We've disabled handling SIGPIPE again. Turns out, writing to broken TCP connections also
+   raised SIGPIPE, so restic exits on the first write to a broken connection. Instead, restic
+   should retry the request.
+
+   https://github.com/restic/restic/issues/1457
+   https://github.com/restic/restic/issues/1466
+   https://github.com/restic/restic/pull/1459
+
+ * Change #1452: Do not save atime by default
+
+   By default, the access time for files and dirs is not saved any more. It is not possible to
+   reliably disable updating the access time during a backup, so for the next backup the access
+   time is different again. This means a lot of metadata is saved. If you want to save the access time
+   anyway, pass `--with-atime` to the `backup` command.
+
+   https://github.com/restic/restic/pull/1452
+
+ * Enhancement #1436: Add code to detect old cache directories
+
+   We've added code to detect old cache directories of repositories that haven't been used in a
+   long time, restic now prints a note when it detects that such dirs exist. Also, the option
+   `--cleanup-cache` was added to automatically remove such directories. That's not a problem
+   because the cache will be rebuild once a repo is accessed again.
+
+   https://github.com/restic/restic/pull/1436
+
+ * Enhancement #1439: Improve cancellation logic
+
+   The cancellation logic was improved, restic can now shut down cleanly when requested to do so
+   (e.g. via ctrl+c).
+
+   https://github.com/restic/restic/pull/1439
+
+ * Enhancement #11: Add the `diff` command
+
+   The command `diff` was added, it allows comparing two snapshots and listing all differences.
+
+   https://github.com/restic/restic/issues/11
+   https://github.com/restic/restic/issues/1460

+=======================================
+
+The following sections list the changes in restic 0.8.0 relevant to
+restic users. The changes are ordered by importance.
+
+Summary
+-------
+
+ * Sec #1445: Prevent writing outside the target directory during restore
+ * Fix #1256: Re-enable workaround for S3 backend
+ * Fix #1291: Reuse backend TCP connections to BackBlaze B2

+ * Enh #1353: Retry failed backend requests
+
+Details
+-------
+
+ * Security #1445: Prevent writing outside the target directory during restore
+
+   A vulnerability was found in the restic restorer, which allowed attackers in special
+   circumstances to restore files to a location outside of the target directory. Due to the
+   circumstances we estimate this to be a low-risk vulnerability, but urge all users to upgrade to
+   the latest version of restic.
+
+   Exploiting the vulnerability requires a Linux/Unix system which saves backups via restic and
+   a Windows systems which restores files from the repo. In addition, the attackers need to be able
+   to create create files with arbitrary names which are then saved to the restic repo. For
+   example, by creating a file named "..\test.txt" (which is a perfectly legal filename on Linux)
+   and restoring a snapshot containing this file on Windows, it would be written to the parent of
+   the target directory.
+
+   We'd like to thank Tyler Spivey for reporting this responsibly!
+
+   https://github.com/restic/restic/pull/1445
+
+ * Bugfix #1256: Re-enable workaround for S3 backend
+
+   We've re-enabled a workaround for `minio-go` (the library we're using to access s3 backends),
+   this reduces memory usage.
+
+   https://github.com/restic/restic/issues/1256
+   https://github.com/restic/restic/pull/1267
+
+ * Bugfix #1291: Reuse backend TCP connections to BackBlaze B2
+
+   A bug was discovered in the library we're using to access Backblaze, it now reuses already
+   established TCP connections which should be a lot faster and not cause network failures any
+   more.
+
+   https://github.com/restic/restic/issues/1291
+   https://github.com/restic/restic/pull/1301
+
+ * Bugfix #1317: Run prune when `forget --prune` is called with just snapshot IDs
+
+   A bug in the `forget` command caused `prune` not to be run when `--prune` was specified without a
+   policy, e.g. when only snapshot IDs that should be forgotten are listed manually.
+
+   https://github.com/restic/restic/pull/1317
+
+ * Bugfix #1437: Remove implicit path `/restic` for the s3 backend
+
+   The s3 backend used the subdir `restic` within a bucket if no explicit path after the bucket name
+   was specified. Since this version, restic does not use this default path any more. If you
+   created a repo on s3 in a bucket without specifying a path within the bucket, you need to add
+   `/restic` at the end of the repository specification to access your repo:
+   `s3:s3.amazonaws.com/bucket/restic`
+
+   https://github.com/restic/restic/issues/1292
+   https://github.com/restic/restic/pull/1437
+
+ * Enhancement #1102: Add subdirectory `ids` to fuse mount
+
+   The fuse mount now has an `ids` subdirectory which contains the snapshots below their (short)
+   IDs.
+
+   https://github.com/restic/restic/issues/1102
+   https://github.com/restic/restic/pull/1299
+   https://github.com/restic/restic/pull/1320
+
+ * Enhancement #1114: Add `--cacert` to specify TLS certificates to check against
+
+   We've added the `--cacert` option which can be used to pass one (or more) CA certificates to
+   restic. These are used in addition to the system CA certificates to verify HTTPS certificates
+   (e.g. for the REST backend).
+
+   https://github.com/restic/restic/issues/1114
+   https://github.com/restic/restic/pull/1276
+
+ * Enhancement #1216: Add upload/download limiting
+
+   We've added support for rate limiting through `--limit-upload` and `--limit-download`
+   flags.
+
+   https://github.com/restic/restic/issues/1216
+   https://github.com/restic/restic/pull/1336
+   https://github.com/restic/restic/pull/1358
+
+ * Enhancement #1271: Cache results for excludes for `backup`
+
+   The `backup` command now caches the result of excludes for a directory.
+
+   https://github.com/restic/restic/issues/1271
+   https://github.com/restic/restic/pull/1326
+
+ * Enhancement #1274: Add `generate` command, replaces `manpage` and `autocomplete`
+
+   The `generate` command has been added, which replaces the now removed commands `manpage` and
+   `autocomplete`. This release of restic contains the most recent manpages in `doc/man` and the
+   auto-completion files for bash and zsh in `doc/bash-completion.sh` and
+   `doc/zsh-completion.zsh`
+
+   https://github.com/restic/restic/issues/1274
+   https://github.com/restic/restic/pull/1282
+
+ * Enhancement #1367: Allow comments in files read from via `--file-from`
+
+   When the list of files/dirs to be saved is read from a file with `--files-from`, comment lines
+   (starting with `#`) are now ignored.
+
+   https://github.com/restic/restic/issues/1367
+   https://github.com/restic/restic/pull/1368
+
+ * Enhancement #448: Sftp backend prompts for password
+
+   The sftp backend now prompts for the password if a password is necessary for login.
+
+   https://github.com/restic/restic/issues/448
+   https://github.com/restic/restic/pull/1270
+
+ * Enhancement #510: Add `dump` command
+
+   We've added the `dump` command which prints a file from a snapshot to stdout. This can e.g. be
+   used to restore files read with `backup --stdin`.
+
+   https://github.com/restic/restic/issues/510
+   https://github.com/restic/restic/pull/1346
+
+ * Enhancement #1040: Add local metadata cache
+
+   We've added a local cache for metadata so that restic doesn't need to load all metadata
+   (snapshots, indexes, ...) from the repo each time it starts. By default the cache is active, but
+   there's a new global option `--no-cache` that can be used to disable the cache. By deafult, the
+   cache a standard cache folder for the OS, which can be overridden with `--cache-dir`. The cache
+   will automatically populate, indexes and snapshots are saved as they are loaded. Cache
+   directories for repos that haven't been used recently can automatically be removed by restic
+   with the `--cleanup-cache` option.
+
+   A related change was to by default create pack files in the repo that contain either data or
+   metadata, not both mixed together. This allows easy caching of only the metadata files. The
+   next run of `restic prune` will untangle mixed files automatically.

+   https://github.com/restic/restic/pull/1436
+   https://github.com/restic/restic/pull/1265
+
+ * Enhancement #1249: Add `latest` symlink in fuse mount
+
+   The directory structure in the fuse mount now exposes a symlink `latest` which points to the
+   latest snapshot in that particular directory.
+
+   https://github.com/restic/restic/pull/1249
+
+ * Enhancement #1269: Add `--compact` to `forget` command
+
+   The option `--compact` was added to the `forget` command to provide the same compact view as the
+   `snapshots` command.
+
+   https://github.com/restic/restic/pull/1269
+
+ * Enhancement #1281: Google Cloud Storage backend needs less permissions
+
+   The Google Cloud Storage backend no longer requires the service account to have the
+   `storage.buckets.get` permission ("Storage Admin" role) in `restic init` if the bucket
+   already exists.
+
+   https://github.com/restic/restic/pull/1281
+
+ * Enhancement #1319: Make `check` print `no errors found` explicitly
+
+   The `check` command now explicetly prints `No errors were found` when no errors could be found.
+
+   https://github.com/restic/restic/issues/1303

+
+Details
+-------
+
+ * Bugfix #1246: List all files stored in Google Cloud Storage
+
+   For large backups stored in Google Cloud Storage, the `prune` command fails because listing
+   only returns the first 1000 files. This has been corrected, no data is lost in the process. In
+   addition, a plausibility check was added to `prune`.

+ * Enh #1203: Print stats on all BSD systems when SIGINFO (ctrl+t) is received
+ * Enh #1205: Allow specifying time/date for a backup with `--time`
+
+Details
+-------
+
+ * Bugfix #1167: Do not create a local repo unless `init` is used
+
+   When a restic command other than `init` is used with a local repository and the repository
+   directory does not exist, restic creates the directory structure. That's an error, only the
+   `init` command should create the dir.
+
+   https://github.com/restic/restic/issues/1167
+   https://github.com/restic/restic/pull/1182
+
+ * Bugfix #1164: Make the `key remove` command behave as documented
+
+   https://github.com/restic/restic/pull/1164
+
+ * Bugfix #1191: Make sure to write profiling files on interrupt
+
+   Since a few releases restic had the ability to write profiling files for memory and CPU usage
+   when `debug` is enabled. It was discovered that when restic is interrupted (ctrl+c is
+   pressed), the proper shutdown hook is not run. This is now corrected.
+
+   https://github.com/restic/restic/pull/1191
+
+ * Enhancement #1132: Make `key` command always prompt for a password
+
+   The `key` command now prompts for a password even if the original password to access a repo has
+   been specified via the `RESTIC_PASSWORD` environment variable or a password file.
+
+   https://github.com/restic/restic/issues/1132
+   https://github.com/restic/restic/pull/1133
+
+ * Enhancement #1179: Resolve name conflicts, append a counter
+
+   https://github.com/restic/restic/issues/1179
+   https://github.com/restic/restic/pull/1209
+
+ * Enhancement #1218: Add `--compact` to `snapshots` command
+
+   The option `--compact` was added to the `snapshots` command to get a better overview of the
+   snapshots in a repo. It limits each snapshot to a single line.
+
+   https://github.com/restic/restic/issues/1218
+   https://github.com/restic/restic/pull/1223
+
+ * Enhancement #317: Add `--exclude-caches` and `--exclude-if-present`
+
+   A new option `--exclude-caches` was added that allows excluding cache directories (that are
+   tagged as such). This is a special case of a more generic option `--exclude-if-present` which
+   excludes a directory if a file with a specific name (and contents) is present.
+
+   https://github.com/restic/restic/issues/317
+   https://github.com/restic/restic/pull/1170
+   https://github.com/restic/restic/pull/1224
+
+ * Enhancement #697: Automatically generate man pages for all restic commands
+
+   https://github.com/restic/restic/issues/697
+   https://github.com/restic/restic/pull/1147
+
+ * Enhancement #1044: Improve `restore`, do not traverse/load excluded directories
+
+   https://github.com/restic/restic/pull/1044
+
+ * Enhancement #1061: Add Dockerfile and official Docker image
+
+   https://github.com/restic/restic/pull/1061
+
+ * Enhancement #1126: Use the standard Go git repository layout, use `dep` for vendoring
+
+   The git repository layout was changed to resemble the layout typically used in Go projects,
+   we're not using `gb` for building restic any more and vendoring the dependencies is now taken
+   care of by `dep`.
+
+   https://github.com/restic/restic/pull/1126
+
+ * Enhancement #1134: Add support for storing backups on Google Cloud Storage
+
+   https://github.com/restic/restic/issues/211
+   https://github.com/restic/restic/pull/1134

+
+ * Enhancement #1144: Properly report errors when reading files with exclude patterns.
+
+   https://github.com/restic/restic/pull/1144
+
+ * Enhancement #1149: Add support for storing backups on Microsoft Azure Blob Storage
+
+   The library we're using to access the service requires Go 1.8, so restic now needs at least Go
+   1.8.
+
+   https://github.com/restic/restic/issues/609
+   https://github.com/restic/restic/pull/1149

+Changelog for restic 0.7.1 (2017-07-22)
+=======================================
+
+The following sections list the changes in restic 0.7.1 relevant to
+restic users. The changes are ordered by importance.
+
+Summary
+-------
+
+ * Fix #1115: Fix `prune`, only include existing files in indexes
+ * Enh #1055: Create subdirs below `data/` for local/sftp backends
+ * Enh #1067: Allow loading credentials for s3 from IAM
+ * Enh #1073: Add `migrate` cmd to migrate from `s3legacy` to `default` layout

+ * Enh #1080: Ignore chmod() errors on filesystems which do not support it
+ * Enh #1082: Print stats on SIGINFO on Darwin and FreeBSD (ctrl+t)
+
+Details
+-------
+
+ * Bugfix #1115: Fix `prune`, only include existing files in indexes
+
+   A bug was found (and corrected) in the index rebuilding after prune, which led to indexes which
+   include blobs that were not present in the repo any more. There were already checks in place
+   which detected this situation and aborted with an error message. A new run of either `prune` or
+   `rebuild-index` corrected the index files. This is now fixed and a test has been added to detect
+   this.
+
+   https://github.com/restic/restic/pull/1115
+
+ * Enhancement #1055: Create subdirs below `data/` for local/sftp backends
+
+   The local and sftp backends now create the subdirs below `data/` on open/init. This way, restic
+   makes sure that they always exist. This is connected to an issue for the sftp server:

+   https://github.com/restic/rest-server/pull/11#issuecomment-309879710
+
+ * Enhancement #1067: Allow loading credentials for s3 from IAM
+
+   When no S3 credentials are specified in the environment variables, restic now tries to load
+   credentials from an IAM instance profile when the s3 backend is used.
+
+   https://github.com/restic/restic/issues/1067
+   https://github.com/restic/restic/pull/1086
+
+ * Enhancement #1073: Add `migrate` cmd to migrate from `s3legacy` to `default` layout
+
+   The `migrate` command for chaning the `s3legacy` layout to the `default` layout for s3
+   backends has been improved: It can now be restarted with `restic migrate --force s3_layout`
+   and automatically retries operations on error.

+Changelog for restic 0.7.0 (2017-07-01)
+=======================================
+
+The following sections list the changes in restic 0.7.0 relevant to
+restic users. The changes are ordered by importance.
+
+Summary
+-------
+
+ * Fix #1013: Switch back to using the high-level minio-go API for s3
+ * Fix #965: Switch to `default` repo layout for the s3 backend
+ * Enh #1021: Detect invalid backend name and print error

+ * Enh #989: Improve performance of the `find` command
+ * Enh #975: Add new backend for OpenStack Swift
+ * Enh #998: Improve performance of the fuse mount
+
+Details
+-------
+
+ * Bugfix #1013: Switch back to using the high-level minio-go API for s3
+
+   For the s3 backend we're back to using the high-level API the s3 client library for uploading
+   data, a few users reported dropped connections (which the library will automatically retry
+   now).
+
+   https://github.com/restic/restic/issues/1013
+   https://github.com/restic/restic/issues/1023
+   https://github.com/restic/restic/pull/1025
+
+ * Bugfix #965: Switch to `default` repo layout for the s3 backend
+
+   The default layout for the s3 backend is now `default` (instead of `s3legacy`). Also, there's a
+   new `migrate` command to convert an existing repo, it can be run like this: `restic migrate
+   s3_layout`
+
+   https://github.com/restic/restic/issues/965
+   https://github.com/restic/restic/pull/1004
+
+ * Enhancement #1021: Detect invalid backend name and print error
+
+   Restic now tries to detect when an invalid/unknown backend is used and returns an error
+   message.
+
+   https://github.com/restic/restic/issues/1021
+   https://github.com/restic/restic/pull/1070
+
+ * Enhancement #1029: Remove invalid pack files when `prune` is run
+
+   The `prune` command has been improved and will now remove invalid pack files, for example files
+   that have not been uploaded completely because a backup was interrupted.
+
+   https://github.com/restic/restic/issues/1029
+   https://github.com/restic/restic/pull/1036
+
+ * Enhancement #512: Add Backblaze B2 backend
+
+   https://github.com/restic/restic/issues/512
+   https://github.com/restic/restic/pull/978
+
+ * Enhancement #636: Add dirs `tags` and `hosts` to fuse mount
+
+   The fuse mount now has two more directories: `tags` contains a subdir for each tag, which in turn
+   contains only the snapshots that have this tag. The subdir `hosts` contains a subdir for each
+   host that has a snapshot, and the subdir contains the snapshots for that host.
+
+   https://github.com/restic/restic/issues/636
+   https://github.com/restic/restic/pull/1050
+
+ * Enhancement #989: Improve performance of the `find` command
+
+   Improved performance for the `find` command: Restic recognizes paths it has already checked
+   for the files in question, so the number of backend requests is reduced a lot.
+
+   https://github.com/restic/restic/issues/989
+   https://github.com/restic/restic/pull/993
+
+ * Enhancement #975: Add new backend for OpenStack Swift
+
+   https://github.com/restic/restic/pull/975
+   https://github.com/restic/restic/pull/648
+
+ * Enhancement #998: Improve performance of the fuse mount
+
+   Listing directories which contain large files now is significantly faster.

+Changelog for restic 0.6.1 (2017-06-01)
+=======================================
+
+The following sections list the changes in restic 0.6.1 relevant to
+restic users. The changes are ordered by importance.
+
+Summary
+-------
+
+ * Enh #985: Allow multiple parallel idle HTTP connections
+ * Enh #981: Remove temporary path from binary in `build.go`
+ * Enh #974: Remove regular status reports
+
+Details
+-------
+
+ * Enhancement #985: Allow multiple parallel idle HTTP connections
+
+   Backends based on HTTP now allow several idle connections in parallel. This is especially
+   important for the REST backend, which (when used with a local server) may create a lot
+   connections and exhaust available ports quickly.
+
+   https://github.com/restic/restic/issues/985
+   https://github.com/restic/restic/pull/986
+
+ * Enhancement #981: Remove temporary path from binary in `build.go`
+
+   The `build.go` now strips the temporary directory used for compilation from the binary. This
+   is the first step in enabling reproducible builds.
+
+   https://github.com/restic/restic/pull/981
+
+ * Enhancement #974: Remove regular status reports
+
+   Regular status report: We've removed the status report that was printed every 10 seconds when
+   restic is run non-interactively. You can still force reporting the current status by sending a
+   `USR1` signal to the process.

+Changelog for restic 0.6.0 (2017-05-29)
+=======================================
+
+The following sections list the changes in restic 0.6.0 relevant to
+restic users. The changes are ordered by importance.
+
+Summary
+-------
+
+ * Enh #957: Make `forget` consistent
+ * Enh #966: Unify repository layout for all backends
+ * Enh #962: Improve memory and runtime for the s3 backend
+
+Details
+-------
+
+ * Enhancement #957: Make `forget` consistent
+
+   The `forget` command was corrected to be more consistent in which snapshots are to be
+   forgotten. It is possible that the new code removes more snapshots than before, so please
+   review what would be deleted by using the `--dry-run` option.
+
+   https://github.com/restic/restic/issues/953
+   https://github.com/restic/restic/pull/957
+
+ * Enhancement #966: Unify repository layout for all backends
+
+   Up to now the s3 backend used a special repository layout. We've decided to unify the repository
+   layout and implemented the default layout also for the s3 backend. For creating a new
+   repository on s3 with the default layout, use `restic -o s3.layout=default init`. For further
+   commands the option is not necessary any more, restic will automatically detect the correct
+   layout to use. A future version will switch to the default layout for new repositories.
+
+   https://github.com/restic/restic/issues/965
+   https://github.com/restic/restic/pull/966
+
+ * Enhancement #962: Improve memory and runtime for the s3 backend
+
+   We've updated the library used for accessing s3, switched to using a lower level API and added
+   caching for some requests. This lead to a decrease in memory usage and a great speedup. In
+   addition, we added benchmark functions for all backends, so we can track improvements over
+   time. The Continuous Integration test service we're using (Travis) now runs the s3 backend
+   tests not only against a Minio server, but also against the Amazon s3 live service, so we should
+   be notified of any regressions much sooner.

+Reporting Bugs
+==============
+
+You've found a bug? Thanks for letting us know so we can fix it! It is a good
+idea to describe in detail how to reproduce the bug (when you know how), what
+environment was used and so on. Please tell us at least the following things:
+
+ * What's the version of restic you used? Please include the output of
+   `restic version` in your bug report.
+ * What commands did you execute to get to where the bug occurred?
+ * What did you expect?
+ * What happened instead?
+ * Are you aware of a way to reproduce the bug?
+
+Remember, the easier it is for us to reproduce the bug, the earlier it will be
+corrected!
+
+In addition, you can compile restic with debug support by running
+`go run build.go -tags debug` and instructing it to create a debug log by
+setting the environment variable `DEBUG_LOG` to a file, e.g. like this:
+
+    $ export DEBUG_LOG=/tmp/restic-debug.log
+    $ restic backup ~/work
+
+Please be aware that the debug log file will contain potentially sensitive
+things like file and directory names, so please either redact it before
+uploading it somewhere or post only the parts that are really relevant.

 Development Environment
 =======================
 
-For development, it is recommended to check out the restic repository within a
-`GOPATH`, an introductory text is
-["How to Write Go Code"](https://golang.org/doc/code.html). It is recommended
-to have a working directory, we're using `~/work/restic` in the following. This
-directory mainly contains the directory `src`, where the source code is stored.
+In order to compile restic with the `go` tool directly, it needs to be checked
+out at the right path within a `GOPATH`. The concept of a `GOPATH` is explained
+in ["How to write Go code"](https://golang.org/doc/code.html).
 
-First, create the necessary directory structure and clone the restic repository
-to the correct location:
+If you do not have a directory with Go code yet, executing the following
+instructions in your shell will create one for you and check out the restic
+repo:
 
-    $ mkdir --parents ~/work/restic/src/github.com/restic
-    $ cd ~/work/restic/src/github.com/restic
+    $ export GOPATH="$HOME/go"
+    $ mkdir -p "$GOPATH/src/github.com/restic"
+    $ cd "$GOPATH/src/github.com/restic"
     $ git clone https://github.com/restic/restic
     $ cd restic
 
-Now we're in the main directory of the restic repository. The last step is to
-set the environment variable `$GOPATH` to the correct value:
+You can then build restic as follows:
 
-    $ export GOPATH=~/work/restic:~/work/restic/src/github.com/restic/restic/Godeps/_workspace
+    $ go build ./cmd/restic
+    $ ./restic version
+    restic compiled manually
+    compiled with go1.8.3 on linux/amd64
 
 The following commands can be used to run all the tests:
 
-    $ go test ./...
-    ok          github.com/restic/restic        8.174s
-    [...]
+    $ go test ./cmd/... ./internal/...
 
-The restic binary can be built from the directory `cmd/restic` this way:
-
-    $ cd cmd/restic
-    $ go build
-    $ ./restic version
-    restic compiled manually on go1.4.2
-
-if you want to run your tests on Linux, OpenBSD or FreeBSD, you can use
-[vagrant](https://www.vagrantup.com/) with the proveded `Vagrantfile` to
-quickly set up VMs and run the tests, e.g.:
-
-    $ vagrant up freebsd
-    [...]
-
-    $ vagrant ssh freebsd -c 'cd restic/restic; go test -v ./...'
-    [...]
+The repository contains two sets of directories with code: `cmd/` and
+`internal/` contain the code written for restic, whereas `vendor/` contains
+copies of libraries restic depends on. The libraries are managed with the
+[`dep`](https://github.com/golang/dep) tool.

-go-flags: a go library for parsing command line arguments
-=========================================================
-
-[![GoDoc](https://godoc.org/github.com/jessevdk/go-flags?status.png)](https://godoc.org/github.com/jessevdk/go-flags) [![Build Status](https://travis-ci.org/jessevdk/go-flags.svg?branch=master)](https://travis-ci.org/jessevdk/go-flags) [![Coverage Status](https://img.shields.io/coveralls/jessevdk/go-flags.svg)](https://coveralls.io/r/jessevdk/go-flags?branch=master)
-
-This library provides similar functionality to the builtin flag library of
-go, but provides much more functionality and nicer formatting. From the
-documentation:
-
-Package flags provides an extensive command line option parser.
-The flags package is similar in functionality to the go builtin flag package
-but provides more options and uses reflection to provide a convenient and
-succinct way of specifying command line options.
-
-Supported features:
-* Options with short names (-v)
-* Options with long names (--verbose)
-* Options with and without arguments (bool v.s. other type)
-* Options with optional arguments and default values
-* Multiple option groups each containing a set of options
-* Generate and print well-formatted help message
-* Passing remaining command line arguments after -- (optional)
-* Ignoring unknown command line options (optional)
-* Supports -I/usr/include -I=/usr/include -I /usr/include option argument specification
-* Supports multiple short options -aux
-* Supports all primitive go types (string, int{8..64}, uint{8..64}, float)
-* Supports same option multiple times (can store in slice or last option counts)
-* Supports maps
-* Supports function callbacks
-* Supports namespaces for (nested) option groups
-
-The flags package uses structs, reflection and struct field tags
-to allow users to specify command line options. This results in very simple
-and concise specification of your application options. For example:
-
-    type Options struct {
-        Verbose []bool `short:"v" long:"verbose" description:"Show verbose debug information"`
-    }
-
-This specifies one option with a short name -v and a long name --verbose.
-When either -v or --verbose is found on the command line, a 'true' value
-will be appended to the Verbose field. e.g. when specifying -vvv, the
-resulting value of Verbose will be {[true, true, true]}.
-
-Example:
---------
-	var opts struct {
-		// Slice of bool will append 'true' each time the option
-		// is encountered (can be set multiple times, like -vvv)
-		Verbose []bool `short:"v" long:"verbose" description:"Show verbose debug information"`
-
-		// Example of automatic marshalling to desired type (uint)
-		Offset uint `long:"offset" description:"Offset"`
-
-		// Example of a callback, called each time the option is found.
-		Call func(string) `short:"c" description:"Call phone number"`
-
-		// Example of a required flag
-		Name string `short:"n" long:"name" description:"A name" required:"true"`
-
-		// Example of a value name
-		File string `short:"f" long:"file" description:"A file" value-name:"FILE"`
-
-		// Example of a pointer
-		Ptr *int `short:"p" description:"A pointer to an integer"`
-
-		// Example of a slice of strings
-		StringSlice []string `short:"s" description:"A slice of strings"`
-
-		// Example of a slice of pointers
-		PtrSlice []*string `long:"ptrslice" description:"A slice of pointers to string"`
-
-		// Example of a map
-		IntMap map[string]int `long:"intmap" description:"A map from string to int"`
-	}
-
-	// Callback which will invoke callto:<argument> to call a number.
-	// Note that this works just on OS X (and probably only with
-	// Skype) but it shows the idea.
-	opts.Call = func(num string) {
-		cmd := exec.Command("open", "callto:"+num)
-		cmd.Start()
-		cmd.Process.Release()
-	}
-
-	// Make some fake arguments to parse.
-	args := []string{
-		"-vv",
-		"--offset=5",
-		"-n", "Me",
-		"-p", "3",
-		"-s", "hello",
-		"-s", "world",
-		"--ptrslice", "hello",
-		"--ptrslice", "world",
-		"--intmap", "a:1",
-		"--intmap", "b:5",
-		"arg1",
-		"arg2",
-		"arg3",
-	}
-
-	// Parse flags from `args'. Note that here we use flags.ParseArgs for
-	// the sake of making a working example. Normally, you would simply use
-	// flags.Parse(&opts) which uses os.Args
-	args, err := flags.ParseArgs(&opts, args)
-
-	if err != nil {
-		panic(err)
-		os.Exit(1)
-	}
-
-	fmt.Printf("Verbosity: %v\n", opts.Verbose)
-	fmt.Printf("Offset: %d\n", opts.Offset)
-	fmt.Printf("Name: %s\n", opts.Name)
-	fmt.Printf("Ptr: %d\n", *opts.Ptr)
-	fmt.Printf("StringSlice: %v\n", opts.StringSlice)
-	fmt.Printf("PtrSlice: [%v %v]\n", *opts.PtrSlice[0], *opts.PtrSlice[1])
-	fmt.Printf("IntMap: [a:%v b:%v]\n", opts.IntMap["a"], opts.IntMap["b"])
-	fmt.Printf("Remaining args: %s\n", strings.Join(args, " "))
-
-	// Output: Verbosity: [true true]
-	// Offset: 5
-	// Name: Me
-	// Ptr: 3
-	// StringSlice: [hello world]
-	// PtrSlice: [hello world]
-	// IntMap: [a:1 b:5]
-	// Remaining args: arg1 arg2 arg3

-Package flags provides an extensive command line option parser.
-The flags package is similar in functionality to the go built-in flag package
-but provides more options and uses reflection to provide a convenient and
-succinct way of specifying command line options.
-
-
-Supported features
-
-The following features are supported in go-flags:
-
-    Options with short names (-v)
-    Options with long names (--verbose)
-    Options with and without arguments (bool v.s. other type)
-    Options with optional arguments and default values
-    Option default values from ENVIRONMENT_VARIABLES, including slice and map values
-    Multiple option groups each containing a set of options
-    Generate and print well-formatted help message
-    Passing remaining command line arguments after -- (optional)
-    Ignoring unknown command line options (optional)
-    Supports -I/usr/include -I=/usr/include -I /usr/include option argument specification
-    Supports multiple short options -aux
-    Supports all primitive go types (string, int{8..64}, uint{8..64}, float)
-    Supports same option multiple times (can store in slice or last option counts)
-    Supports maps
-    Supports function callbacks
-    Supports namespaces for (nested) option groups
-
-Additional features specific to Windows:
-    Options with short names (/v)
-    Options with long names (/verbose)
-    Windows-style options with arguments use a colon as the delimiter
-    Modify generated help message with Windows-style / options
-
-
-Basic usage
-
-The flags package uses structs, reflection and struct field tags
-to allow users to specify command line options. This results in very simple
-and concise specification of your application options. For example:
-
-    type Options struct {
-        Verbose []bool `short:"v" long:"verbose" description:"Show verbose debug information"`
-    }
-
-This specifies one option with a short name -v and a long name --verbose.
-When either -v or --verbose is found on the command line, a 'true' value
-will be appended to the Verbose field. e.g. when specifying -vvv, the
-resulting value of Verbose will be {[true, true, true]}.
-
-Slice options work exactly the same as primitive type options, except that
-whenever the option is encountered, a value is appended to the slice.
-
-Map options from string to primitive type are also supported. On the command
-line, you specify the value for such an option as key:value. For example
-
-    type Options struct {
-        AuthorInfo string[string] `short:"a"`
-    }
-
-Then, the AuthorInfo map can be filled with something like
--a name:Jesse -a "surname:van den Kieboom".
-
-Finally, for full control over the conversion between command line argument
-values and options, user defined types can choose to implement the Marshaler
-and Unmarshaler interfaces.
-
-
-Available field tags
-
-The following is a list of tags for struct fields supported by go-flags:
-
-    short:            the short name of the option (single character)
-    long:             the long name of the option
-    required:         whether an option is required to appear on the command
-                      line. If a required option is not present, the parser will
-                      return ErrRequired (optional)
-    description:      the description of the option (optional)
-    long-description: the long description of the option. Currently only
-                      displayed in generated man pages (optional)
-    no-flag:          if non-empty this field is ignored as an option (optional)
-
-    optional:       whether an argument of the option is optional (optional)
-    optional-value: the value of an optional option when the option occurs
-                    without an argument. This tag can be specified multiple
-                    times in the case of maps or slices (optional)
-    default:        the default value of an option. This tag can be specified
-                    multiple times in the case of slices or maps (optional)
-    default-mask:   when specified, this value will be displayed in the help
-                    instead of the actual default value. This is useful
-                    mostly for hiding otherwise sensitive information from
-                    showing up in the help. If default-mask takes the special
-                    value "-", then no default value will be shown at all
-                    (optional)
-    env:            the default value of the option is overridden from the
-                    specified environment variable, if one has been defined.
-                    (optional)
-    env-delim:      the 'env' default value from environment is split into
-                    multiple values with the given delimiter string, use with
-                    slices and maps (optional)
-    value-name:     the name of the argument value (to be shown in the help)
-                    (optional)
-
-    base: a base (radix) used to convert strings to integer values, the
-          default base is 10 (i.e. decimal) (optional)
-
-    ini-name:       the explicit ini option name (optional)
-    no-ini:         if non-empty this field is ignored as an ini option
-                    (optional)
-
-    group:                when specified on a struct field, makes the struct
-                          field a separate group with the given name (optional)
-    namespace:            when specified on a group struct field, the namespace
-                          gets prepended to every option's long name and
-                          subgroup's namespace of this group, separated by
-                          the parser's namespace delimiter (optional)
-    command:              when specified on a struct field, makes the struct
-                          field a (sub)command with the given name (optional)
-    subcommands-optional: when specified on a command struct field, makes
-                          any subcommands of that command optional (optional)
-    alias:                when specified on a command struct field, adds the
-                          specified name as an alias for the command. Can be
-                          be specified multiple times to add more than one
-                          alias (optional)
-    positional-args:      when specified on a field with a struct type,
-                          uses the fields of that struct to parse remaining
-                          positional command line arguments into (in order
-                          of the fields). If a field has a slice type,
-                          then all remaining arguments will be added to it.
-                          Positional arguments are optional by default,
-                          unless the "required" tag is specified together
-                          with the "positional-args" tag (optional)
-    positional-arg-name:  used on a field in a positional argument struct; name
-                          of the positional argument placeholder to be shown in
-                          the help (optional)
-
-
-Either the `short:` tag or the `long:` must be specified to make the field eligible as an
-option.
-
-
-Option groups
-
-Option groups are a simple way to semantically separate your options. All
-options in a particular group are shown together in the help under the name
-of the group. Namespaces can be used to specify option long names more
-precisely and emphasize the options affiliation to their group.
-
-There are currently three ways to specify option groups.
-
-    1. Use NewNamedParser specifying the various option groups.
-    2. Use AddGroup to add a group to an existing parser.
-    3. Add a struct field to the top-level options annotated with the
-       group:"group-name" tag.
-
-
-
-Commands
-
-The flags package also has basic support for commands. Commands are often
-used in monolithic applications that support various commands or actions.
-Take git for example, all of the add, commit, checkout, etc. are called
-commands. Using commands you can easily separate multiple functions of your
-application.
-
-There are currently two ways to specify a command.
-
-    1. Use AddCommand on an existing parser.
-    2. Add a struct field to your options struct annotated with the
-       command:"command-name" tag.
-
-The most common, idiomatic way to implement commands is to define a global
-parser instance and implement each command in a separate file. These
-command files should define a go init function which calls AddCommand on
-the global parser.
-
-When parsing ends and there is an active command and that command implements
-the Commander interface, then its Execute method will be run with the
-remaining command line arguments.
-
-Command structs can have options which become valid to parse after the
-command has been specified on the command line, in addition to the options
-of all the parent commands. I.e. considering a -v flag on the parser and an
-add command, the following are equivalent:
-
-    ./app -v add
-    ./app add -v
-
-However, if the -v flag is defined on the add command, then the first of
-the two examples above would fail since the -v flag is not defined before
-the add command.
-
-
-Completion
-
-go-flags has builtin support to provide bash completion of flags, commands
-and argument values. To use completion, the binary which uses go-flags
-can be invoked in a special environment to list completion of the current
-command line argument. It should be noted that this `executes` your application,
-and it is up to the user to make sure there are no negative side effects (for
-example from init functions).
-
-Setting the environment variable `GO_FLAGS_COMPLETION=1` enables completion
-by replacing the argument parsing routine with the completion routine which
-outputs completions for the passed arguments. The basic invocation to
-complete a set of arguments is therefore:
-
-    GO_FLAGS_COMPLETION=1 ./completion-example arg1 arg2 arg3
-
-where `completion-example` is the binary, `arg1` and `arg2` are
-the current arguments, and `arg3` (the last argument) is the argument
-to be completed. If the GO_FLAGS_COMPLETION is set to "verbose", then
-descriptions of possible completion items will also be shown, if there
-are more than 1 completion items.
-
-To use this with bash completion, a simple file can be written which
-calls the binary which supports go-flags completion:
-
-    _completion_example() {
-        # All arguments except the first one
-        args=("${COMP_WORDS[@]:1:$COMP_CWORD}")
-
-        # Only split on newlines
-        local IFS=$'\n'
-
-        # Call completion (note that the first element of COMP_WORDS is
-        # the executable itself)
-        COMPREPLY=($(GO_FLAGS_COMPLETION=1 ${COMP_WORDS[0]} "${args[@]}"))
-        return 0
-    }
-
-    complete -F _completion_example completion-example
-
-Completion requires the parser option PassDoubleDash and is therefore enforced if the environment variable GO_FLAGS_COMPLETION is set.
-
-Customized completion for argument values is supported by implementing
-the flags.Completer interface for the argument value type. An example
-of a type which does so is the flags.Filename type, an alias of string
-allowing simple filename completion. A slice or array argument value
-whose element type implements flags.Completer will also be completed.

-
-The juju/errors provides an easy way to annotate errors without losing the
-orginal error context.
-
-The exported `New` and `Errorf` functions are designed to replace the
-`errors.New` and `fmt.Errorf` functions respectively. The same underlying
-error is there, but the package also records the location at which the error
-was created.
-
-A primary use case for this library is to add extra context any time an
-error is returned from a function.
-
-
-	    if err := SomeFunc(); err != nil {
-		    return err
-		}
-
-This instead becomes:
-
-
-	    if err := SomeFunc(); err != nil {
-		    return errors.Trace(err)
-		}
-
-which just records the file and line number of the Trace call, or
-
-
-	    if err := SomeFunc(); err != nil {
-		    return errors.Annotate(err, "more context")
-		}
-
-which also adds an annotation to the error.
-
-When you want to check to see if an error is of a particular type, a helper
-function is normally exported by the package that returned the error, like the
-`os` package does.  The underlying cause of the error is available using the
-`Cause` function.
-
-
-	os.IsNotExist(errors.Cause(err))
-
-The result of the `Error()` call on an annotated error is the annotations joined
-with colons, then the result of the `Error()` method for the underlying error
-that was the cause.
-
-
-	err := errors.Errorf("original")
-	err = errors.Annotatef(err, "context")
-	err = errors.Annotatef(err, "more context")
-	err.Error() -> "more context: context: original"
-
-Obviously recording the file, line and functions is not very useful if you
-cannot get them back out again.
-
-
-	errors.ErrorStack(err)
-
-will return something like:
-
-
-	first error
-	github.com/juju/errors/annotation_test.go:193:
-	github.com/juju/errors/annotation_test.go:194: annotation
-	github.com/juju/errors/annotation_test.go:195:
-	github.com/juju/errors/annotation_test.go:196: more context
-	github.com/juju/errors/annotation_test.go:197:
-
-The first error was generated by an external system, so there was no location
-associated. The second, fourth, and last lines were generated with Trace calls,
-and the other two through Annotate.
-
-Sometimes when responding to an error you want to return a more specific error
-for the situation.
-
-
-	    if err := FindField(field); err != nil {
-		    return errors.Wrap(err, errors.NotFoundf(field))
-		}
-
-This returns an error where the complete error stack is still available, and
-`errors.Cause()` will return the `NotFound` error.
-
-
-
-
-
-
-## func AlreadyExistsf
-``` go
-func AlreadyExistsf(format string, args ...interface{}) error
-```
-AlreadyExistsf returns an error which satisfies IsAlreadyExists().
-
-
-## func Annotate
-``` go
-func Annotate(other error, message string) error
-```
-Annotate is used to add extra context to an existing error. The location of
-the Annotate call is recorded with the annotations. The file, line and
-function are also recorded.
-
-For example:
-
-
-	if err := SomeFunc(); err != nil {
-	    return errors.Annotate(err, "failed to frombulate")
-	}
-
-
-## func Annotatef
-``` go
-func Annotatef(other error, format string, args ...interface{}) error
-```
-Annotatef is used to add extra context to an existing error. The location of
-the Annotate call is recorded with the annotations. The file, line and
-function are also recorded.
-
-For example:
-
-
-	if err := SomeFunc(); err != nil {
-	    return errors.Annotatef(err, "failed to frombulate the %s", arg)
-	}
-
-
-## func Cause
-``` go
-func Cause(err error) error
-```
-Cause returns the cause of the given error.  This will be either the
-original error, or the result of a Wrap or Mask call.
-
-Cause is the usual way to diagnose errors that may have been wrapped by
-the other errors functions.
-
-
-## func DeferredAnnotatef
-``` go
-func DeferredAnnotatef(err *error, format string, args ...interface{})
-```
-DeferredAnnotatef annotates the given error (when it is not nil) with the given
-format string and arguments (like fmt.Sprintf). If *err is nil, DeferredAnnotatef
-does nothing. This method is used in a defer statement in order to annotate any
-resulting error with the same message.
-
-For example:
-
-
-	defer DeferredAnnotatef(&err, "failed to frombulate the %s", arg)
-
-
-## func Details
-``` go
-func Details(err error) string
-```
-Details returns information about the stack of errors wrapped by err, in
-the format:
-
-
-	[{filename:99: error one} {otherfile:55: cause of error one}]
-
-This is a terse alternative to ErrorStack as it returns a single line.
-
-
-## func ErrorStack
-``` go
-func ErrorStack(err error) string
-```
-ErrorStack returns a string representation of the annotated error. If the
-error passed as the parameter is not an annotated error, the result is
-simply the result of the Error() method on that error.
-
-If the error is an annotated error, a multi-line string is returned where
-each line represents one entry in the annotation stack. The full filename
-from the call stack is used in the output.
-
-
-	first error
-	github.com/juju/errors/annotation_test.go:193:
-	github.com/juju/errors/annotation_test.go:194: annotation
-	github.com/juju/errors/annotation_test.go:195:

-	github.com/juju/errors/annotation_test.go:197:
-
-
-## func Errorf
-``` go
-func Errorf(format string, args ...interface{}) error
-```
-Errorf creates a new annotated error and records the location that the
-error is created.  This should be a drop in replacement for fmt.Errorf.
-
-For example:
-
-
-	return errors.Errorf("validation failed: %s", message)
-
-
-## func IsAlreadyExists
-``` go
-func IsAlreadyExists(err error) bool
-```
-IsAlreadyExists reports whether the error was created with
-AlreadyExistsf() or NewAlreadyExists().
-
-
-## func IsNotFound
-``` go
-func IsNotFound(err error) bool
-```
-IsNotFound reports whether err was created with NotFoundf() or
-NewNotFound().
-
-
-## func IsNotImplemented
-``` go
-func IsNotImplemented(err error) bool
-```
-IsNotImplemented reports whether err was created with
-NotImplementedf() or NewNotImplemented().
-
-
-## func IsNotSupported
-``` go
-func IsNotSupported(err error) bool
-```
-IsNotSupported reports whether the error was created with
-NotSupportedf() or NewNotSupported().
-
-
-## func IsNotValid
-``` go
-func IsNotValid(err error) bool
-```
-IsNotValid reports whether the error was created with NotValidf() or
-NewNotValid().
-
-
-## func IsUnauthorized
-``` go
-func IsUnauthorized(err error) bool
-```
-IsUnauthorized reports whether err was created with Unauthorizedf() or
-NewUnauthorized().
-
-
-## func Mask
-``` go
-func Mask(other error) error
-```
-Mask hides the underlying error type, and records the location of the masking.
-
-
-## func Maskf
-``` go
-func Maskf(other error, format string, args ...interface{}) error
-```
-Mask masks the given error with the given format string and arguments (like
-fmt.Sprintf), returning a new error that maintains the error stack, but
-hides the underlying error type.  The error string still contains the full
-annotations. If you want to hide the annotations, call Wrap.
-
-
-## func New
-``` go
-func New(message string) error
-```
-New is a drop in replacement for the standard libary errors module that records
-the location that the error is created.
-
-For example:
-
-
-	return errors.New("validation failed")
-
-
-## func NewAlreadyExists
-``` go
-func NewAlreadyExists(err error, msg string) error
-```
-NewAlreadyExists returns an error which wraps err and satisfies
-IsAlreadyExists().
-
-
-## func NewNotFound
-``` go
-func NewNotFound(err error, msg string) error
-```
-NewNotFound returns an error which wraps err that satisfies
-IsNotFound().
-
-
-## func NewNotImplemented
-``` go
-func NewNotImplemented(err error, msg string) error
-```
-NewNotImplemented returns an error which wraps err and satisfies
-IsNotImplemented().
-
-
-## func NewNotSupported
-``` go
-func NewNotSupported(err error, msg string) error
-```
-NewNotSupported returns an error which wraps err and satisfies
-IsNotSupported().
-
-
-## func NewNotValid
-``` go
-func NewNotValid(err error, msg string) error
-```
-NewNotValid returns an error which wraps err and satisfies IsNotValid().
-
-
-## func NewUnauthorized
-``` go
-func NewUnauthorized(err error, msg string) error
-```
-NewUnauthorized returns an error which wraps err and satisfies
-IsUnauthorized().
-
-
-## func NotFoundf
-``` go
-func NotFoundf(format string, args ...interface{}) error
-```
-NotFoundf returns an error which satisfies IsNotFound().
-
-
-## func NotImplementedf
-``` go
-func NotImplementedf(format string, args ...interface{}) error
-```
-NotImplementedf returns an error which satisfies IsNotImplemented().
-
-
-## func NotSupportedf
-``` go
-func NotSupportedf(format string, args ...interface{}) error
-```
-NotSupportedf returns an error which satisfies IsNotSupported().
-
-
-## func NotValidf
-``` go
-func NotValidf(format string, args ...interface{}) error
-```
-NotValidf returns an error which satisfies IsNotValid().
-
-
-## func Trace
-``` go
-func Trace(other error) error
-```
-Trace adds the location of the Trace call to the stack.  The Cause of the
-resulting error is the same as the error parameter.  If the other error is
-nil, the result will be nil.
-
-For example:
-
-
-	if err := SomeFunc(); err != nil {
-	    return errors.Trace(err)
-	}
-
-
-## func Unauthorizedf
-``` go
-func Unauthorizedf(format string, args ...interface{}) error
-```
-Unauthorizedf returns an error which satisfies IsUnauthorized().
-
-
-## func Wrap
-``` go
-func Wrap(other, newDescriptive error) error
-```
-Wrap changes the Cause of the error. The location of the Wrap call is also
-stored in the error stack.
-
-For example:
-
-
-	if err := SomeFunc(); err != nil {
-	    newErr := &packageError{"more context", private_value}
-	    return errors.Wrap(err, newErr)
-	}
-
-
-## func Wrapf
-``` go
-func Wrapf(other, newDescriptive error, format string, args ...interface{}) error
-```
-Wrapf changes the Cause of the error, and adds an annotation. The location
-of the Wrap call is also stored in the error stack.
-
-For example:
-
-
-	if err := SomeFunc(); err != nil {
-	    return errors.Wrapf(err, simpleErrorType, "invalid value %q", value)
-	}
-
-
-
-## type Err
-``` go
-type Err struct {
-    // contains filtered or unexported fields
-}
-```
-Err holds a description of an error along with information about
-where the error was created.
-
-It may be embedded in custom error types to add extra information that
-this errors package can understand.
-
-
-
-
-
-
-
-
-
-### func NewErr
-``` go
-func NewErr(format string, args ...interface{}) Err
-```
-NewErr is used to return an Err for the purpose of embedding in other
-structures.  The location is not specified, and needs to be set with a call
-to SetLocation.
-
-For example:
-
-
-	type FooError struct {
-	    errors.Err
-	    code int
-	}
-	
-	func NewFooError(code int) error {
-	    err := &FooError{errors.NewErr("foo"), code}
-	    err.SetLocation(1)
-	    return err
-	}
-
-
-
-
-### func (\*Err) Cause
-``` go
-func (e *Err) Cause() error
-```
-The Cause of an error is the most recent error in the error stack that
-meets one of these criteria: the original error that was raised; the new
-error that was passed into the Wrap function; the most recently masked
-error; or nil if the error itself is considered the Cause.  Normally this
-method is not invoked directly, but instead through the Cause stand alone
-function.
-
-
-
-### func (\*Err) Error
-``` go
-func (e *Err) Error() string
-```
-Error implements error.Error.
-
-
-
-### func (\*Err) Location
-``` go
-func (e *Err) Location() (filename string, line int)
-```
-Location is the file and line of where the error was most recently
-created or annotated.
-
-
-
-### func (\*Err) Message
-``` go
-func (e *Err) Message() string
-```
-Message returns the message stored with the most recent location. This is
-the empty string if the most recent call was Trace, or the message stored
-with Annotate or Mask.
-
-
-
-### func (\*Err) SetLocation
-``` go
-func (e *Err) SetLocation(callDepth int)
-```
-SetLocation records the source location of the error at callDepth stack
-frames above the call.
-
-
-
-### func (\*Err) StackTrace
-``` go
-func (e *Err) StackTrace() []string
-```
-StackTrace returns one string for each location recorded in the stack of
-errors. The first value is the originating error, with a line for each
-other annotation or tracing of the error.
-
-
-
-### func (\*Err) Underlying
-``` go
-func (e *Err) Underlying() error
-```
-Underlying returns the previous error in the error stack, if any. A client
-should not ever really call this method.  It is used to build the error
-stack and should not be introspected by client calls.  Or more
-specifically, clients should not depend on anything but the `Cause` of an
-error.

-`os` package does.  The underlying cause of the error is available using the
-`Cause` function.
-
-	os.IsNotExist(errors.Cause(err))
-
-The result of the `Error()` call on an annotated error is the annotations joined
-with colons, then the result of the `Error()` method for the underlying error
-that was the cause.
-
-	err := errors.Errorf("original")
-	err = errors.Annotatef(err, "context")
-	err = errors.Annotatef(err, "more context")
-	err.Error() -> "more context: context: original"
-
-Obviously recording the file, line and functions is not very useful if you
-cannot get them back out again.
-
-	errors.ErrorStack(err)
-
-will return something like:
-
-	first error
-	github.com/juju/errors/annotation_test.go:193:
-	github.com/juju/errors/annotation_test.go:194: annotation
-	github.com/juju/errors/annotation_test.go:195:
-	github.com/juju/errors/annotation_test.go:196: more context
-	github.com/juju/errors/annotation_test.go:197:
-
-The first error was generated by an external system, so there was no location
-associated. The second, fourth, and last lines were generated with Trace calls,
-and the other two through Annotate.
-
-Sometimes when responding to an error you want to return a more specific error
-for the situation.
-
-    if err := FindField(field); err != nil {
-	    return errors.Wrap(err, errors.NotFoundf(field))
-	}
-
-This returns an error where the complete error stack is still available, and
-`errors.Cause()` will return the `NotFound` error.
