xclip is a command line interface to the X11
clipboard. It can also be used for copying files,
as an alternative to sftp/scp, thus avoiding
password prompts when X11 forwarding has already
been setup.

The use of getop_long() has been changed to
XrmParseCommand(), a function in xlib, for
portability (apparently System V Unix derived
machines don't have getopt_long(), but
XrmParseCommand() is part of xlib, and hence
should always be available). XrmParseCommand
ignores ambiguous options (-ver gets ignored,
instead of going to -verbose or -version), and
doesn't do multiple options with one hyphen (-if
instead of -i -f). The -out (out mode) and -filter
(print stdin back to stdout) options have been added.
