[RFC 0/3] Prepare the Makefile and scripts/ for releasing

[RFC 0/3] Prepare the Makefile and scripts/ for releasing

[Alejandro Colomar]

Hi!

I'm preparing the Makefile and scripts to be able to release
without hidden scripts, just from the repository.  I put in the
Makefile everything that can be done incrementally (or at least
idempotently, since tar(1) doesn't really allow incrementally
creating an archive, unlike ar(1)), and in scripts what can't
(i.e., the COLOPHON generation).

I tried to follow conventions (from GNU and others) as much as
possible.

The COLOPHON format was kept as I see it in existing pages in my
system, with one difference: until now, the URI in the COLOPHON
wasn't being enclosed in <> (the script didn't use .UR/.UE).
I fixed that.

Now one can generate DISTFILES (.tar, .tar.gz, and .tar.xz files)
simply with the following commands.  The version number is taken
from git.

	./scripts/append_COLOPHON.sh
	make dist-gz

Of course, the generation of the COLOPHON is not a dependency for
the generation of the tarballs, but it's likely that both commands
will be run together.


Cheers,

Alex

[PATCH 2/3] scripts/append_COLOPHON.sh: Add script to append the COLOPHON section

[Alejandro Colomar]

I first implemented it using cat <<-, but sed(1) is around 5 times
faster, so even if it's a bit more complex and slightly less
readable, let's use sed(1).
