I wanted to add option groups to fcore, and also make sure that the 
utility options come first.  I've included a draft patch.

This came up in conversation with Tom and Andrew. This required a little 
bit of hacking in bindir/fcore, util/CommandlineParser and 
util/ProcStopUntil. I've added the output and the patch that makes this 
happen. I have not checked it in. Please pay special attention to my 
comments around parse() as I am not sure this is the best place to add 
the default options. They have to be added "late" otherwise they will be 
added at the top of the --help output. There is a lot of weird indenting 
going on in the right help column, but this was happening beforehand and 
is another unrelated (but hopefully soon to be fixed) bug.

./frysk_bin/frysk-core/frysk/bindir/fcore --help

Usage: fcore <PID>

Corefile options:
  -a, -allmaps                   Include ALL process readable maps.
  -s, -segments =PATTERN        use PATTERN as regex to define maps 
inclusion.
  -o, -outputfile <filename>     Sets the name of  the corefile.

Frysk specific options:
  -debug <COMP=LEVEL,...>       Set debug-tracing of COMP to LEVEL.
                                  LEVEL can be [ NONE | FINE | FINEST ];
                                  default is FINE.
                                  Example: debug frysk.rsl=FINE
  -noexe                        Do not attempt to read an executable for a
                                  corefile
  -exe <executable>             Specify the full path of the executable 
to read
  -sysroot <path to sysroot>    Special root directory

Standard options:
  -help       print this help, then exit
  -version    print version number, then exit
