+# SYNOPSIS
+#
+# AX_CHECK_ENABLE_DEBUG([enable by default=yes/info/profile/no], [ENABLE DEBUG VARIABLES ...], [DISABLE DEBUG VARIABLES NDEBUG ...], [IS-RELEASE])
+#
+# DESCRIPTION
+#
+# Check for the presence of an --enable-debug option to configure, with
+# the specified default value used when the option is not present. Return
+# the value in the variable $ax_enable_debug.
+#
+# Specifying 'yes' adds '-g -O0' to the compilation flags for all
+# languages. Specifying 'info' adds '-g' to the compilation flags.
+# Specifying 'profile' adds '-g -pg' to the compilation flags and '-pg' to
+# the linking flags. Otherwise, nothing is added.
+#
+# Define the variables listed in the second argument if debug is enabled,
+# defaulting to no variables. Defines the variables listed in the third
+# argument if debug is disabled, defaulting to NDEBUG. All lists of
+# variables should be space-separated.
+#
+# If debug is not enabled, ensure AC_PROG_* will not add debugging flags.
+# Should be invoked prior to any AC_PROG_* compiler checks.
+#
+# IS-RELEASE can be used to change the default to 'no' when making a
+# release. Set IS-RELEASE to 'yes' or 'no' as appropriate. By default, it
+# uses the value of $ax_is_release, so if you are using the AX_IS_RELEASE
+# macro, there is no need to pass this parameter.

+# SYNOPSIS
+#
+# AX_IS_RELEASE(POLICY)
+#
+# DESCRIPTION
+#
+# Determine whether the code is being configured as a release, or from
+# git. Set the ax_is_release variable to 'yes' or 'no'.
+#
+# If building a release version, it is recommended that the configure
+# script disable compiler errors and debug features, by conditionalising
+# them on the ax_is_release variable. If building from git, these
+# features should be enabled.
+#
+# The POLICY parameter specifies how ax_is_release is determined. It can
+# take the following values:
+#
+# * git-directory: ax_is_release will be 'no' if a '.git' directory exists
+# * minor-version: ax_is_release will be 'no' if the minor version number
+# in $PACKAGE_VERSION is odd; this assumes
+# $PACKAGE_VERSION follows the 'major.minor.micro' scheme
+# * micro-version: ax_is_release will be 'no' if the micro version number
+# in $PACKAGE_VERSION is odd; this assumes
+# $PACKAGE_VERSION follows the 'major.minor.micro' scheme
+# * always: ax_is_release will always be 'yes'
+# * never: ax_is_release will always be 'no'
+#
+# Other policies may be added in future.
