-  X_X04SA_do_casave.py - Script to execute a casave command.
-  ====================
-
-  Usage:
-
-    %s [<options>] -- <arguments-for-casave>
-
-  Description:
-    casave seems to be not 100%% reliable, at least when run from
-    spec via a "unix" command. It sometimes hangs up.
-
-    X_X04SA_do_casave.py will spawn a child process to run casave
-    with the given <arguments-for-casave>. If the process does
-    not terminate within the timeout (default = 5 secs), the
-    child process will be killed.
-
-    If the child process is killed, <arguments-for-casave> will
-    be parsed, looking for a -asciiout option. If it is found,
-    a file of the given name will be created containing the text
-
-             casave killed at <date> <time>
-
-  Options:
-    -h               generate this help text.
-    -v               display version information.
-    --debug          turn on debug printout.
-    --timeout=<secs> specify a timeout. Default = 5 secs.
-    --               marks the start of args for casave.
