+# 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.
