usage: rush purge [-h] [--unsafe]
The "rush purge" command is used to delete temporary files created by Rush.
This is useful if you are having problems and suspect that cache files may be
corrupt.
Optional arguments:
-h, --help Show this help message and exit.
--unsafe (UNSAFE!) Also delete shared files such as the package manager
instances stored in the ".rush" folder in the user's home
directory. This is a more aggressive fix that is NOT SAFE to
run in a live environment because it will cause other
concurrent Rush processes to fail.
