ClearCase::CtCmd is self-documenting through the Perl POD (Plain Old
Documentation) facility.  After installation, "perldoc ClearCase::CtCmd"
will display the self-documentation.  Before installation the command
"perldoc -F CtCmd.pm" may be used from the installation directory.

ClearCase::CtCmd does not save/restore user signal handlers upon 
entrance/exit.  Users are, of course, able to explictly
restore their signal handlers with the $SIG{<signal>} = <handler ref>
mechanism after each invocation of ClearCase::CtCmd::exec(),
but user signal handlers are modified by the ClearCase libraries
called by ClearCase::CtCmd, if the signal handler for signals 1, 2, 3 
or 15 is set to SIG_IGN ( that is, $SIG{[1|2|3|15]} = 'IGNORE' ) 
the signal handler will be saved during and after 
an invocation of ClearCase::CtCmd::exec.
