#
# To use in your project, import this file in your git repo's toplevel,
# then do "make -f git.mk".  This modifies all Makefile.am files in
# your project to -include git.mk.  Remember to add that line to new
# Makefile.am files you create in your project, or just rerun the
# "make -f git.mk".
#
# This enables automatic .gitignore generation.  If you need to ignore
# more files, add them to the GITIGNOREFILES variable in your Makefile.am.
# But think twice before doing that.  If a file has to be in .gitignore,
# chances are very high that it's a generated file and should be in one
# of MOSTLYCLEANFILES, CLEANFILES, DISTCLEANFILES, or MAINTAINERCLEANFILES.
#
# The only case that you need to manually add a file to GITIGNOREFILES is
# when remove files in one of mostlyclean-local, clean-local, distclean-local,
# or maintainer-clean-local make targets.
#
# Note that for files like editor backup, etc, there are better places to
# ignore them.  See "man gitignore".
#
# If "make maintainer-clean" removes the files but they are not recognized
# by this script (that is, if "git status" shows untracked files still), send
# me the output of "git status" as well as your Makefile.am and Makefile for
# the directories involved and I'll diagnose.
#
# For a list of toplevel files that should be in MAINTAINERCLEANFILES, see
# Makefile.am.sample in the git.mk git repo.
#
# Don't EXTRA_DIST this file.  It is supposed to only live in git clones,
# not tarballs.  It serves no useful purpose in tarballs and clutters the
# build dir.
#
# This file knows how to handle autoconf, automake, libtool, gtk-doc,
# gnome-doc-utils, yelp.m4, mallard, intltool, gsettings, dejagnu.
#
# This makefile provides the following targets:
#
# - all: "make all" will build all gitignore files.
# - gitignore: makes all gitignore files in the current dir and subdirs.
# - .gitignore: make gitignore file for the current dir.
# - gitignore-recurse: makes all gitignore files in the subdirs.
#
# KNOWN ISSUES:
#
# - Recursive configure doesn't work as $(top_srcdir)/git.mk inside the
#   submodule doesn't find us.  If you have configure.{in,ac} files in
#   subdirs, add a proxy git.mk file in those dirs that simply does:
#   "include $(top_srcdir)/../git.mk".  Add more ..'s to your taste.
#   And add those files to git.  See vte/gnome-pty-helper/git.mk for
#   example.
