+Usage: fixskel [-c|-i|-r]
+
+ -c    Check symlinks for sanity
+ -i    Install symlinks
+ -r    Remove symlinks
+
+This script will adjust the bash-config symlinks in /usr/share/skel
+so that new users will be set up automatically. This is a companion
+script to 'fixusers', which will set up existing users.
+
+This script will avoid tampering with files that it thinks are
+manually added. Use -c to check, and verify the files manually
+afterwards.
