If true the shell +# commands in ACTION-IF-TRUE are executed. If not the shell commands in +# ACTION-IF-FALSE are run. Note if $PERL is not set (for example by +# calling AC_CHECK_PROG, or AC_PATH_PROG), AC_CHECK_PROG(PERL, perl, perl) +# will be run. +# +# MODULES is a space separated list of module names. To check for a +# minimum version of a module, append the version number to the module +# name, separated by an equals sign. +# +# Example: +# +# AX_PROG_PERL_MODULES( Text::Wrap Net::LDAP=1.0.3, , +# AC_MSG_WARN(Need some Perl modules) +# +# LICENSE +# +# Copyright (c) 2009 Dean Povey <povey@wedgetail.com> +# +# Copying and distribution of this file, with or without modification, are +# permitted in any medium without royalty provided the copyright notice +# and this notice are preserved.
