  12 /* DESCRIPTION
  13 /*      debug_process() runs a debugger, as specified in the
  14 /*      \fIdebugger_command\fR configuration variable.
  15 /*
  16 /*      Examples of non-interactive debuggers are call tracing tools
  17 /*      such as: trace, strace or truss.
  18 /*
  19 /*      Examples of interactive debuggers are xxgdb, xxdbx, and so on.
