SYNOPSIS
      xcallouts <search pattern>
      or
      xcallouts    (when writing to a pipe)

DESCRIPTION
      Prints all running callouts matching regexp pattern. Note that a void
      search pattern means no matches.
      When writing to a pipe, all call_outs will be printed and the search
      pattern is not allowed.

EXAMPLES
      xcallouts obj   Show all callouts with the string "obj" in it.
      xcallouts .     Show all callouts. Please never do this if it isn't
                      really neccessary. It just costs time - and what do you
                      want to do with this mass of information?
