-# 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.
-#
-#     AX_IS_RELEASE([git-directory])
-#     AX_CHECK_ENABLE_DEBUG()
