@majorheading Synopsis

@smallexample
AX_PROG_PERL_VERSION([VERSION],[ACTION-IF-TRUE],[ACTION-IF-FALSE])
@end smallexample

@majorheading Description

Makes sure that perl supports the version indicated. 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
running AC_CHECK_PROG or AC_PATH_PROG) the macro will fail.

Example:

@smallexample
  AC_PATH_PROG([PERL],[perl])
  AX_PROG_PERL_VERSION([5.8.0],[ ... ],[ ... ])
@end smallexample

This will check to make sure that the perl you have supports at least
version 5.8.0.

NOTE: This macro uses the $PERL variable to perform the check.
AX_WITH_PERL can be used to set that variable prior to running this
macro. The $PERL_VERSION variable will be valorized with the detected
version.
