#
# 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>.

# SYNOPSIS
#
# AX_PYTHON_DEVEL([version])
#
# DESCRIPTION
#
# Note: Defines as a precious variable "PYTHON_VERSION". Don't override it
# in your configure.ac.
#
# This macro checks for Python and tries to get the include path to
# 'Python.h'. It provides the $(PYTHON_CPPFLAGS) and $(PYTHON_LDFLAGS)
# output variables. It also exports $(PYTHON_EXTRA_LIBS) and
# $(PYTHON_EXTRA_LDFLAGS) for embedding Python in your code.
#
# You can search for some particular version of Python by passing a
# parameter to this macro, for example ">= '2.3.1'", or "== '2.4'". Please
# note that you *have* to pass also an operator along with the version to
# match, and pay special attention to the single quotes surrounding the
# version number. Don't use "PYTHON_VERSION" for this: that environment
# variable is declared as precious and thus reserved for the end-user.
#
# This macro should work for all versions of Python >= 2.1.0. As an end
# user, you can disable the check for the python version by setting the
# PYTHON_NOVERSIONCHECK environment variable to something else than the
# empty string.
#
# If you need to use this macro for an older Python version, please
# contact the authors. We're always open for feedback.

# AX_WITH_RUBY([VALUE-IF-NOT-FOUND],[PATH])
#
# DESCRIPTION
#
# Locates an installed Ruby binary, placing the result in the precious
# variable $RUBY. Accepts a present $RUBY, then --with-ruby, and failing
# that searches for ruby in the given path (which defaults to the system
# path). If ruby is found, $RUBY is set to the full path of the binary; if
# it is not found $RUBY is set to VALUE-IF-NOT-FOUND if provided,
# unchanged otherwise.

# 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 |
