usage: rush link [-h] [-f]
Create node_modules symlinks for all projects. This operation is normally
performed automatically as part of "rush install" or "rush update". You
should only need to use "rush link" if you performed "rush unlink" for some
reason, or if you specified the "--no-link" option for "rush install" or
-h, --help Show this help message and exit.
-f, --force Deletes and recreates all links, even if the filesystem state
seems to indicate that this is unnecessary.
