Usage: $(basename $0) [OPTION] PROFILE
Options:
  --create,--add,--new          Creates a new mod profile under PROFILE. If this is your first,
                                your current mods will be moved to the profile and the necessary 
                                symbolic links set up automatically.
  --help,-h                     Prints this help.
  --link                        Checks if the necessary folders are sym linked. If not, creates
                                them. Will link to \`current\` unless a PROFILE is given.
  --open,--cd                   Opens a new shell in the "%AppData%/Local/Larian Studios" folder.
  --switch                      Switch to PROFILE.

Empty argument list is equivalent to "--list". A single argument is equivalent to
"--switch <argument>".
