 By default, the [environment variable processing](../configuration/interpolating.md) is performed on synchronized files that match the expected suffixes in `REPLACE_ENV_SUFFIXES` (by default "yml,yaml,txt,cfg,conf,properties,hjson,json,tml,toml") and are not excluded by `REPLACE_ENV_VARIABLES_EXCLUDES` and `REPLACE_ENV_VARIABLES_EXCLUDE_PATHS`. This processing can be disabled by setting `REPLACE_ENV_DURING_SYNC` to `false`.
 
-If you want old mods/plugins to be removed before the content is brought over from those attach points, then add `-e REMOVE_OLD_MODS=TRUE`. You can fine tune the removal process by specifying the `REMOVE_OLD_MODS_INCLUDE` and `REMOVE_OLD_MODS_EXCLUDE` variables, which are comma separated lists of file glob patterns. If a directory is excluded, then it and all of its contents are excluded. By default, only jars are removed.
