+#   AX_PROG_PERL_MODULES([MODULES], [ACTION-IF-TRUE], [ACTION-IF-FALSE])
+#
+# DESCRIPTION
+#
+#   Checks to see if the given perl modules are available. 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)

+# This is what autoupdate's m4 run will expand.  It fires
+# the warning (with _au_warn_XXX), outputs it into the
+# updated configure.ac (with AC_DIAGNOSE), and then outputs
+# the replacement expansion.
+
+
+# This is an auxiliary macro that is also run when
+# autoupdate runs m4.  It simply calls m4_warning, but
+# we need a wrapper so that each warning is emitted only
+# once.  We break the quoting in m4_warning's argument in
+# order to expand this macro's arguments, not AU_DEFUN's.
+
+
+# Finally, this is the expansion that is picked up by
+# autoconf.  It tells the user to run autoupdate, and
+# then outputs the replacement expansion.  We do not care
+# about autoupdate's warning because that contains
+# information on what to do *after* running autoupdate.
