Change/Remove the security CATEGORY for each FILE/USER.

Use +/- to add/remove categories from a FILE/USER.

Note:  When  removing  a  category you must specify - -- on the command
line before using the -Category syntax.  This tells  the  command  that
you  have  finished  entering options and are now specifying a category
name instead.

-d     delete the category from each FILE/USER.

-L     list available categories.

-l     Tells chcat to operate on users instead of files.
