 the crossloop skills do exist which does do this to an extent - it at least
compresses (gzips) the core files and renames them.  It wouldn't be hard to
modify the script to do other stuff also.

 With the core file, you can then get the stack trace at a later time (presuming
the server it was generated from has not changed.).

 Now it would not be hard to extend that script to also do something like:
 gdb --command=/some/file server/crossfire core > /some/other/file

 where the --command file lists the commands you want gdb to do (probably where,
q).  I'm not sure if I would want to default crossloop scripts to do this -
after all, gdb isn't installed on every system.
