3# This script is used by test/Makefile to check whether a sane 'pod2man'
4# is installed.
5# ('make install' should not try to run 'pod2man' if it does not exist or if
6# it is a broken 'pod2man' version that is known to cause trouble. if we find
7# the system 'pod2man' to be broken, we use our own copy instead)
8#
9# In any case, output an appropriate command line for running (or not
10# running) pod2man.
