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. -+# -+# LICENSE -+# -+# Copyright (c) 2008 Tim Toolan <toolan@ele.uri.edu> -+# -+# 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.
