-# 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_LIB_POSTGRESQL([MINIMUM-VERSION],[ACTION-IF-FOUND],[ACTION-IF-NOT-FOUND])
-#
-# DESCRIPTION
-#
-# This macro provides tests of availability of PostgreSQL 'libpq' library
-# of particular version or newer.
-#
-# AX_LIB_POSTGRESQL macro takes only one argument which is optional. If
-# there is no required version passed, then macro does not run version
-# test.
-#
-# The --with-postgresql option takes one of three possible values:
-#
-# no - do not check for PostgreSQL client library
-#
-# yes - do check for PostgreSQL library in standard locations (pg_config
-# should be in the PATH)
-#
-# path - complete path to pg_config utility, use this option if pg_config
-# can't be found in the PATH (You could set also PG_CONFIG variable)
-#
-# This macro calls:
-#
-# AC_SUBST(POSTGRESQL_CPPFLAGS)
-# AC_SUBST(POSTGRESQL_LDFLAGS)
-# AC_SUBST(POSTGRESQL_LIBS)
-# AC_SUBST(POSTGRESQL_VERSION)
-#
-# And sets:
-#
-# HAVE_POSTGRESQL
-#
-# It execute if found ACTION-IF-FOUND (empty by default) and
-# ACTION-IF-NOT-FOUND (AC_MSG_FAILURE by default) if not found.

-# DX_PDF_FEATURE(ON|OFF)
-# DX_PS_FEATURE(ON|OFF)
-#
-# DESCRIPTION
-#
-# The DX_*_FEATURE macros control the default setting for the given
-# Doxygen feature. Supported features are 'DOXYGEN' itself, 'DOT' for
-# generating graphics, 'HTML' for plain HTML, 'CHM' for compressed HTML
-# help (for MS users), 'CHI' for generating a separate .chi file by the
-# .chm file, and 'MAN', 'RTF', 'XML', 'PDF' and 'PS' for the appropriate
-# output formats. The environment variable DOXYGEN_PAPER_SIZE may be
-# specified to override the default 'a4wide' paper size.
-#
-# By default, HTML, PDF and PS documentation is generated as this seems to
-# be the most popular and portable combination. MAN pages created by
-# Doxygen are usually problematic, though by picking an appropriate subset
-# and doing some massaging they might be better than nothing. CHM and RTF
-# are specific for MS (note that you can't generate both HTML and CHM at
-# the same time). The XML is rather useless unless you apply specialized
-# post-processing to it.
-#
-# The macros mainly control the default state of the feature. The use can
-# override the default by specifying --enable or --disable. The macros
-# ensure that contradictory flags are not given (e.g.,
-# --enable-doxygen-html and --enable-doxygen-chm,
-# --enable-doxygen-anything with --disable-doxygen, etc.) Finally, each
-# feature will be automatically disabled (with a warning) if the required
-# programs are missing.
-#
-# Once all the feature defaults have been specified, call DX_INIT_DOXYGEN
-# with the following parameters: a one-word name for the project for use
-# as a filename base etc., an optional configuration file name (the
-# default is '$(srcdir)/Doxyfile', the same as Doxygen's default), and an
-# optional output directory name (the default is 'doxygen-doc'). To run
-# doxygen multiple times for different configuration files and output
-# directories provide more parameters: the second, forth, sixth, etc
-# parameter are configuration file names and the third, fifth, seventh,
-# etc parameter are output directories. No checking is done to catch
-# duplicates.
-#
-# Automake Support
-#
-# The DX_RULES substitution can be used to add all needed rules to the
-# Makefile. Note that this is a substitution without being a variable:
-# only the @DX_RULES@ syntax will work.
-#
-# The provided targets are:
-#
-# doxygen-doc: Generate all doxygen documentation.
-#
-# doxygen-run: Run doxygen, which will generate some of the
-# documentation (HTML, CHM, CHI, MAN, RTF, XML)
-# but will not do the post processing required
-# for the rest of it (PS, PDF).
-#
-# doxygen-ps: Generate doxygen PostScript documentation.
-#
-# doxygen-pdf: Generate doxygen PDF documentation.
-#
-# Note that by default these are not integrated into the automake targets.
-# If doxygen is used to generate man pages, you can achieve this
-# integration by setting man3_MANS to the list of man pages generated and
-# then adding the dependency:
-#
-# $(man3_MANS): doxygen-doc
-#
-# This will cause make to run doxygen and generate all the documentation.
-#
-# The following variable is intended for use in Makefile.am:
-#
-# DX_CLEANFILES = everything to clean.
-#
-# Then add this variable to MOSTLYCLEANFILES.

-# LIBCURL_CHECK_CONFIG ([DEFAULT-ACTION], [MINIMUM-VERSION],
-# [ACTION-IF-YES], [ACTION-IF-NO])
-# ----------------------------------------------------------
-# 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.
