#!/usr/bin/perl
#
# An interesting command to run under k5start or krenew to perform various
# tests. It takes on the command-line a file into which to write, and into
# that file, it puts its PID, its current working directory, and its ticket
# cache. When it gets a HUP or INT signal, it writes into that file. When it
# gets a TERM signal, it writes into that file and exits.
