#
# SYNOPSIS
#
# AX_CHECK_GIRS_GJS(MODULE, API_VERSION [, MODULE, API_VERSION...])
#
# DESCRIPTION
#
# Check that the GObject Introspection module $MODULE is importable in GJS
# (GNOME's JavaScript engine, https://wiki.gnome.org/Projects/Gjs). The
# API version must be $API_VERSION.
#
# GObject Introspection
# (https://wiki.gnome.org/Projects/GObjectIntrospection) is a tool for
# generating bindings from C libraries to higher-level languages. The
# bindings live in a GObject Introspection repository (GIR) file, which is
# what this macro checks.
#
# Note that for the purposes of GObject Introspection, the API version is
# different from the release version. For example, GTK currently has API
# version 3.0, but that could mean any release from the 3.0, 3.2, 3.4,...
# series. To check for specific API that was added in a later version, use
# AX_CHECK_GIR_SYMBOLS_GJS.
#
# Example:
#
# AX_CHECK_GIRS_GJS([Gdk], [3.0],
# [Gtk], [3.0])
#
# NOTE: This macro depends on AX_PROG_GJS.
