# SYNOPSIS
#
# AX_COMPARE_VERSION(VERSION_A, OP, VERSION_B, [ACTION-IF-TRUE], [ACTION-IF-FALSE])
#
# DESCRIPTION
#
# This macro compares two version strings. Due to the various number of
# minor-version numbers that can exist, and the fact that string
# comparisons are not compatible with numeric comparisons, this is not
# necessarily trivial to do in a autoconf script. This macro makes doing
# these comparisons easy.
#
# The six basic comparisons are available, as well as checking equality
# limited to a certain number of minor-version levels.
#
# The operator OP determines what type of comparison to do, and can be one
# of:
#
# eq - equal (test A == B)
# ne - not equal (test A != B)
# le - less than or equal (test A <= B)
# ge - greater than or equal (test A >= B)
# lt - less than (test A < B)
# gt - greater than (test A > B)
#
# Additionally, the eq and ne operator can have a number after it to limit
# the test to that number of minor versions.
#
# eq0 - equal up to the length of the shorter version
# ne0 - not equal up to the length of the shorter version
# eqN - equal up to N sub-version levels
# neN - not equal up to N sub-version levels
#
# When the condition is true, shell commands ACTION-IF-TRUE are run,
# otherwise shell commands ACTION-IF-FALSE are run. The environment
# variable 'ax_compare_version' is always set to either 'true' or 'false'
# as well.
#
# Examples:
#
# AX_COMPARE_VERSION([3.15.7],[lt],[3.15.8])
# AX_COMPARE_VERSION([3.15],[lt],[3.15.8])
#
# would both be true.
#
# AX_COMPARE_VERSION([3.15.7],[eq],[3.15.8])
# AX_COMPARE_VERSION([3.15],[gt],[3.15.8])
#
# would both be false.
#
# AX_COMPARE_VERSION([3.15.7],[eq2],[3.15.8])
#
# would be true because it is only comparing two minor versions.
#
# AX_COMPARE_VERSION([3.15.7],[eq0],[3.15])
#
# would be true because it is only comparing the lesser number of minor
# versions of the two values.
#
# Note: The characters that separate the version numbers do not matter. An
# empty string is the same as version 0. OP is evaluated by autoconf, not
# configure, so must be a string, not a variable.
#
# The author would like to acknowledge Guido Draheim whose advice about
# the m4_case and m4_ifvaln functions make this macro only include the
# portions necessary to perform the specific comparison specified by the
# OP argument in the final configure script.

# SYNOPSIS
#
# AX_PROG_PERL_VERSION([VERSION],[ACTION-IF-TRUE],[ACTION-IF-FALSE])
#
# 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:
#
# AC_PATH_PROG([PERL],[perl])
# AX_PROG_PERL_VERSION([5.8.0],[ ... ],[ ... ])
#
# 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.
