NOTES
lockit has been tested under Digital UNIX, IRIX, and UNICOS.
Suggestions for enhancements or bug reports can be directed to

This command utilizes the cci command parser utilized by non-UNIX operating
systems instead of the traditional UNIX getopt() parsing. Options have been
defined to "look like" UNIX style options, but can be spelled out or gen-
erally abbreviated. For example '-p' is the same as '-password'. Because
of this multiple options must be space separated and the hyphen is part of
the option name. Also because of this order of options is irrelevant.
