#****h* Cygclasses/gnome2.cygclass
#  SYNOPSIS
#  inherit gnome2
#  DESCRIPTION
#  The GNOME project provides a full-featured X desktop with a wide variety
#  of applications, built on an object-oriented library stack based on GLib
#  and the GTK+ toolkit.  Most packages are written in C and are built with
#  an autotools-based system with some additional tools.
#
#  This cygclass manages the building of most GNOME-based packages.
#  INHERITS
#  autotools.cygclass, gnome.org.cygclass
#****

inherit gnome.org

#****C* gnome2.cygclass/gnome2_autoreconf
#  SYNOPSIS
#  gnome2_autoreconf
#  DESCRIPTION
#  Updates the build system with gnome-autogen.sh.  gnome2_autoreconf must be
#  run in the directory containing the top-level configure.ac or configure.in
#  (usually $S).
#  WARNING
#  Skipping this step is strongly discouraged.  Patches to configure.ac, aclocal
#  macros, or Makefile.am files will not take effect until their tools have been
#  regenerated.  Also, Cygwin's libtool package often includes patches which
#  are not yet available in the latest upstream release, so libraries may not
#  be built optimally, or even correctly, without this step having been run.
#  The same applies for some of the GNOME build tools as well.
#  REQUIRES
#  autoconf, automake, gettext-devel, gnome-common, gnome-doc-utils, gtk-doc,
#  intltool, libglib2.0-devel, libtool, pkg-config.
#  SEE ALSO
#  cygautoreconf

#  By default, gnome-autogen.sh will retool the working directory's and any
#  subdirectories containing a configure.ac/configure.in which may be configured
#  separately with an AC_CONFIG_SUBDIRS.  If a subdirectory need not be
#  retooled (e.g. it will not built for whatever reason), or it does not use
#  autotools (e.g. the libdb included in evolution), define this variable to
#  the subdirectories to skip, relative to the directory where gnome2_autoreconf
#  will be run (usually $S).
