++# 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.
