  10 # The canonical source for this file is pango/git.mk, or whereever the
  11 # header of pango/git.mk suggests in the future.
  12 #
  13 # To use in your project, import this file in your git repo's toplevel,
  14 # then do "make -f git.mk".  This modifies all Makefile.am files in
  15 # your project to include git.mk.
  16 #
  17 # This enables automatic .gitignore generation.  If you need to ignore
  18 # more files, add them to the GITIGNOREFILES variable in your Makefile.am.
  19 # But think twice before doing that.  If a file has to be in .gitignore,
  20 # chances are very high that it's a generated file and should be in one
  21 # of MOSTLYCLEANFILES, CLEANFILES, DISTCLEANFILES, or MAINTAINERCLEANFILES.
  22 #
  23 # The only case that you need to manually add a file to GITIGNOREFILES is
  24 # when remove files in one of mostlyclean-local, clean-local, distclean-local,
  25 # or maintainer-clean-local.
  26 #
  27 # Note that for files like editor backup, etc, there are better places to
  28 # ignore them.  See "man gitignore".
  29 #
  30 # If "make maintainer-clean" removes the files but they are not recognized
  31 # by this script (that is, if "git status" shows untracked files still), send
  32 # me the output of "git status" as well as your Makefile.am and Makefile for
  33 # the directories involved.
  34 #
  35 # For a list of toplevel files that should be in MAINTAINERCLEANFILES, see
  36 # pango/Makefile.am.
  37 #
  38 # Don't EXTRA_DIST this file.  It is supposed to only live in git clones,
  39 # not tarballs.  It serves no useful purpose in tarballs and clutters the
  40 # build dir.
  41 #
  42 # This file knows how to handle autoconf, automake, libtool, gtk-doc,
  43 # gnome-doc-utils, intltool.
  44 #
  45 #
  46 # KNOWN ISSUES:
  47 #
  48 # - Recursive configure doesn't work as $(top_srcdir)/git.mk inside the
  49 #   submodule doesn't find us.  If you have configure.{in,ac} files in
  50 #   subdirs, add a proxy git.mk file in those dirs that simply does:
  51 #   "include $(top_srcdir)/../git.mk".  Add more ..'s to your taste.
  52 #   And add those files to git.  See vte/gnome-pty-helper/git.mk for
  53 #   example.
