+# The canonical source for this file is pango/git.mk, or whereever the
+# header of pango/git.mk suggests in the future.
+#
+# 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.
+#
+# 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.
+#
+# 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.
+#
+# For a list of toplevel files that should be in MAINTAINERCLEANFILES, see
+# pango/Makefile.am.
+#
+# 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, intltool.
+#
+#
+# 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.
