Hello,

Following the great DVC development, I made some adaptations to the
dgnushack.el, for now it's called package-maint.el, if you have a
better ideas for the name, thanks to submit... ;-)

The goal is to make it more general, it can group some common tricks
for GNU Emacs vs. XEmacs and specificities about versions.

A package maintainer must provide a package-specific helper wich
require package-maint.el and set the package-maint-pkg variable which
is the actual package name, it's used for autoloads.

Taking DVC as an example, we have in the Makefile:
FLAGS = -batch -q -no-site-file -no-init-file -l $(srcdir)/dvc-build.el

EMACS_COMP = lispdir=$(lispdir) srcdir=$(srcdir) $(EMACS_PROG) $(FLAGS)

all: clean dvc-load.el
        $(EMACS_COMP) -f package-maint-compile


dvc-load.el:
        $(EMACS_COMP) -f package-maint-make-cus-load $(srcdir)
        $(EMACS_COMP) -f package-maint-make-auto-load $(srcdir)
        $(EMACS_COMP) -f package-maint-make-load


dvc-build.el do package specific stuffs like adding or removing .el
files, depending of the presence or not of a library.

I submit this to Lars Magne Ingebrigtsen, he suggest me to post this
to Emacs and XEmacs mailing lists.

So now, I'm waiting your comments/ideas/what you want.

Attached are the dvc-build.el and package-maint.el.

Regards.

What does dgnushack.el do?

How does this relate to Emacs development?

You've lost me.

Distributed Version Control, an evolution of Xtla with more tools
supported (bzr, mercurial, darcs): http://wiki.gnuarch.org/xtla#DVC

dgnushack.el handle autoloads generation and byte-compilation of Gnus.

Such tool may be integrated to Emacs to help package maintainer, it
simplify packages Makefiles and permit code reuse, it can handle well
know tricks for version compatibilities GNU Emacs vs. XEmacs.

I'm really sorry, I'll try to do better:

In DVC we had static build dependencies in Makefiles.

Now, we provide a dvc-build.el which define the package name and
require package-maint.

So in Makfile we can call package-maint-make-{cus,auto}-load and
package-maint-compile.

It avoids complex rules in Makefile, dependencies are automatically
resolved, and when some files are changed, it clean their .elc files
and .elc files which depends on previous...

Hope it's better, I don't want to make you waste your time ;-).

Regards.
