+# 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_WITH_PROG([VARIABLE],[program],[VALUE-IF-NOT-FOUND],[PATH])
+#
+# DESCRIPTION
+#
+# Locates an installed program binary, placing the result in the precious
+# variable VARIABLE. Accepts a present VARIABLE, then --with-program, and
+# failing that searches for program in the given path (which defaults to
+# the system path). If program is found, VARIABLE is set to the full path
+# of the binary; if it is not found VARIABLE is set to VALUE-IF-NOT-FOUND
+# if provided, unchanged otherwise.
+#
+# A typical example could be the following one:
+#
+# AX_WITH_PROG(PERL,perl)
+#
+# NOTE: This macro is based upon the original AX_WITH_PYTHON macro from
+# Dustin J. Mitchell <dustin@cs.uchicago.edu>.

+# ----------------------------------------------------------
+# David Shaw <dshaw@jabberwocky.com> May-09-2006
+#
+# Checks for libcurl. DEFAULT-ACTION is the string yes or no to
+# specify whether to default to --with-libcurl or --without-libcurl.
+# If not supplied, DEFAULT-ACTION is yes. MINIMUM-VERSION is the
+# minimum version of libcurl to accept. Pass the version as a regular
+# version number like 7.10.1. If not supplied, any version is
+# accepted. ACTION-IF-YES is a list of shell commands to run if
+# libcurl was successfully found and passed the various tests.
+# ACTION-IF-NO is a list of shell commands that are run otherwise.
+# Note that using --without-libcurl does run ACTION-IF-NO.
+#
+# This macro #defines HAVE_LIBCURL if a working libcurl setup is
+# found, and sets @LIBCURL@ and @LIBCURL_CPPFLAGS@ to the necessary
+# values. Other useful defines are LIBCURL_FEATURE_xxx where xxx are
+# the various features supported by libcurl, and LIBCURL_PROTOCOL_yyy
+# where yyy are the various protocols supported by libcurl. Both xxx
+# and yyy are capitalized. See the list of AH_TEMPLATEs at the top of
+# the macro for the complete list of possible defines. Shell
+# variables $libcurl_feature_xxx and $libcurl_protocol_yyy are also
+# defined to 'yes' for those features and protocols that were found.
+# Note that xxx and yyy keep the same capitalization as in the
+# curl-config list (e.g. it's "HTTP" and not "http").
+#
+# Users may override the detected values by doing something like:
+# LIBCURL="-lcurl" LIBCURL_CPPFLAGS="-I/usr/myinclude" ./configure
+#
+# For the sake of sanity, this macro assumes that any libcurl that is
+# found is after version 7.7.2, the first version that included the
+# curl-config script. Note that it is very important for people
+# packaging binary versions of libcurl to include this script!
+# Without curl-config, we can only guess what protocols are available,
+# or use curl_version_info to figure it out at runtime.
