Hi,
maintenance of RefTeX will likely be continued by the AUCTeX project.
On the AUCTeX developers list it is currently being discussed how
maintenance of RefTeX will be done in its own CVS repository.
Something it hasn't had before. Since RefTeX is also present in the
CVS repository of Emacs there might be the need to synchronize both
repositories to some extent.
What I am particularly concerned about is how maintainers of RefTeX
will be informed about changes made in Emacs' repository and how those
changes will get propagated back to RefTeX's repository. AFAIK such
synchronization is handled automatically for Gnus by Miles. Would it
be possible and sensible to provide something like this for RefTeX as
well? How do other projects with repositories outside of Emacs, like
CC mode or MH-E, handle this?

How 'bout using the Emacs-CVS as *the* repository of RefTeX?

I would rather have the maintenance of RefTeX done in the Emacs repository.

There will be standalone releases of RefTeX. That means files for
building and installing RefTeX as well as files like README, INSTALL,
etc. would have to be added to Emacs' repository. Those would mostly
be superfluous in an Emacs release and would have to be excluded from
pretest and release tarballs, unless they are considered only a minor
annoyance.
And we'll probably have to jump through some hoops for building
documentation and putting it into a RefTeX tarball as reftex.texi
currently is located in the man directory.
Then there might be the problem that RefTeX is not in a releasable
state at the time an Emacs release is about to happen. Suppose I
would have had a major and risky change for RefTeX waiting to be
checked in about a year ago and held it back because Emacs is about to
be released. I'd probably still not have it checked in. Such a
situation nothing I'd be looking forward to. Of course in an urgent
case one can back out such changes, but if you can avoid it ...
What about branching? IIUC CVS branches can only be created for a
whole module. Would it be okay to create a branch for all of Emacs if
one for RefTeX only were necessary?
Another issue might be that it will be harder for people to grab the
RefTeX sources from CVS if there is a fix they are interested in. At
least with the current structure where the documentation is in a
different directory they'd have to check out the reftex directory (to
be created) and the documentation separately.
If RefTeX is to be maintained in Emacs' repository I'd actually like
to have all files (including documentation) in one dedicated
directory.

Why? What problems is this going to solve that cannot be solved by
telling people to fetch files from the Emacs CVS?

I already answered part of that question in my last mail. Apart from
that there are many users who are not really acquainted with CVS
(okay, there's the web interface) and with "installing" and
byte-compiling single files. And if those users manage to do that
(probably by handholding them through the process) they'll get some
hodgepodge of files from releases and CVS. And providing support for
such hodgepodge installations will be quite a nightmare. I'd really,
_really_ like to avoid such a mess.

But you might need to do that anyway, since some Emacs features used
by RefTeX will require a newer Emacs.
Besides, why not couple them? What's the problem?

What, the need to get several files from different directories?
That's a non-issue, since a problem that urges a user to fetch a newer
file is normally solved in a single directory, if not a single file.
There's no need to fetch the docs if the problem is in Lisp.

This whole mess (and then some) will be completely avoided if you
decide to stick with Emacs releases. If you don't, releasing interim
versions will get you at least some of the trouble, since users will
be installing those versions in several Emacs versions, and you will
have problem knowing which ones (as many people nowadays use the CVS
code).
I really, _really_ urge you to reconsider.

RefTeX should be able to be used with both Emacs and XEmacs.
Therefore we'll need to cater for less capable Emacs releases anyway.

The release cycle of Emacs is simply too long.

Which brings us back to the problem with a hodgepodge of files. With
AUCTeX we are constantly having problems with people picking up
outdated documentation from the web instead of using the documents
accompanying each release, which are up-to-date and correctly reflect
the features and customization options. Now you are suggesting to
introduce such incompatibilities with the integrated documentation as
well? This is not good.

We'll be defining which versions of Emacs and XEmacs RefTeX will be
compatible with, just like we are doing it now with AUCTeX.

RefTeX has always had a life outside the Emacs CVS repository,
to make it run with XEmacs and with non-CVS emacs. It is
still fully compatible with Emacs 21, and it caters for XEmacs
as well.
There are many people who use RefTeX but still use Emacs 21,
and even after the 22 release, this will be true for quite a
while. I wanted to get bug fixes and new features to these users.
Since Emacs does not have a packaging system that allows the user
to easily update a package, and since the release cycle is
(at least currently) extremely long, distributions outside
of Emacs have always been necessary.
So even up to now, RefTeX has had its own CVS, into which I
have merged any changes done on the Emacs side. So nothing
fundamental will change once the AUCTeX project takes over
maintenance and distribution.

The people most likely to maintain it actively in future are AUCTeX
developers. Almost no maintenance has happened in the Emacs
repository up to now.
RefTeX is released standalone (unsynchronized with Emacs releases),
and creating its tarballs and stuff requires Makefiles and similar
that are not present in the Emacs tree.
RefTeX also is maintained for XEmacs. What we have in Emacs is just a
fraction of the whole of RefTeX.
I don't think that maintaining the whole in the Emacs repository is
likely to lead to the best results, since RefTeX is not released just
for Emacs, and even should work with more than one Emacs version.

Ralf said Emacs release cycle is too slow, but now you say that there
are many RefTeX users that still use Emacs 21. This sounds like a
contradiction to me.
Anyway, I just wanted to say that developing an Emacs package outside
Emacs bears additional burden. It is up to you to decide whether that
burden is justified.

Then there might be the problem that RefTeX is not in a releasable
state at the time an Emacs release is about to happen.
This is exactly why it is bad to maintain parts of Emacs in a separate
repository. Every such package causes difficulty for Emacs releases.
What about branching? IIUC CVS branches can only be created for a
whole module. Would it be okay to create a branch for all of Emacs if
one for RefTeX only were necessary?
Yes, it is ok.

If the part is maintained in a separate repository it is possible to
check code into Emacs' repository when it is in releasable state,
e.g. when a separate release of the part is being made. Then one can
go on developing in the separate repository without endangering Emacs'
state as a whole. Thus, in Emacs there there would be releasable code
of the package at any time. With such a policy I would not expect the
difficulty you mentioned to appear.

As Carsten wrote, RefTeX has been mainained outside of Emacs and seen
releases independent of Emacs ever since. So there currently is no
problem with the length of Emacs' release cycle. There would be a
problem, however, if one followed your suggestion not ot release
RefTeX independently of Emacs anymore.

Having RefTeX on a separate release cycle than Emacs allows people to
keep a stable Emacs base system, but pick up RefTeX improvements
without needing to upgrade everything else that comes with Emacs at
the same time. It also allows people to get RefTeX updates without
waiting years for an Emacs release. Many people don't want to track
Emacs CVS, but would be willing to track released updates of a
specific component.
Carsten once made some changes to improve indexing a specific case for
me, and it was very nice that I could get them without going into CVS
or waiting for an Emacs release.

Maybe we could use admin/reftex/* for such files. (admin/ is excluded

When using admin/reftex/*, I don't see that it's much harder than in a
separate repository.
With Richard's okay to a RefTeX-only branch in Emacs CVS, this sounds
like a good solution to me. The branch would be e.g. "reftex_devel"
and the Emacs trunk would correspond to the current stable RefTeX
branch. Keeping both in the same CVS repository would also make it
easier to merge bugfixes and administrative changes (update of
copyright notices, etc.) from Emacs trunk to "reftex_devel" much
easier (maybe Miles could do this like he does with the unicode branch
and other branches).
Bye, Reiner.

People who don't want to (or can't [1]) upgrade to Emacs 22 are not
necessarily the same people as the ones who want a never version of
$package.
Some other example: Emacs 21 comes with Gnus 5.9 which was released in
1999 [2]. In case of [1], (s)he can still install a much more recent
stable Gnus (5.10.8, released 2006; only bug fixes to 5.10.1, release
2003).

ACK. If Miles wouldn't do the work of syncing Gnus and Emacs
repositories, it would again imply much work for the next but one
Emacs release.
Bye, Reiner.
[1] E.g. if the sysadmin doesn't wan to install non-release software.
[2] Not only the long release cycle of Emacs, but also the long
release cycle of Gnus is responsible for this.

Those can easily be put into the `admin' subdirectory which is not included

Right, you'd have to do a bit of extra work to bring the various files from
`admin', `man', `lisp', ... into a single directory when building
the tarball.

That's what branches are for. No problem here.

You understand incorrectly. In CVS each file is handled separately (so to
a large extent, the notion of "module" only exists in the documentation of
CVS rather than in its code and behavior), so you can have separate branches
on a file-by-file basis. It's generally saner to have the same branches on
"every" file, but it's perfectly OK to have a branch only on a well-defined
subset of the files, such as have a RefTeX-only branch on the
RefTeX-related files.

That would be OK as well, although not needed.

That would probably not be an option. Although, starting from the Arch
version of Emacs's repository, you could easily create an Arch archive for
RefTeX which automatically tracks all the RefTeX files (and only them), and
placed in a single directory or any other way you want.

If the part is maintained in a separate repository it is possible to
check code into Emacs' repository when it is in releasable state,
e.g. when a separate release of the part is being made. Then one can
go on developing in the separate repository without endangering Emacs'
state as a whole. Thus, in Emacs there there would be releasable code
of the package at any time.
In theory, this is good. But what often happens is that people
develop a package on its own, and we have trouble getting the changes
into Emacs.
Right now there are fixes in CC mode which have not been installed
in Emacs, and that is one of the things our release is waiting for.

I'm not sure if I understood correctly. You mean to put only the
build files, auxiliary files (README, INSTALL, etc.) and ChangeLog
into admin/reftex?

What I dislike about it is that the files will be scattered throughout
Emacs' repository. This makes fetching the "package" RefTeX from CVS
much more complicated. And with the branch it would get even harder
if people want to fetch a development version. Also stuff like `C-x 4
a' won't work with such a file layout and a single ChangeLog file.

There are many people who use RefTeX but still use Emacs 21,

This may require branching *inside* the Emacs CVS tree, i.e. to
create an `emacs-21' maintenance branch, but it's not something
unheard of. It's exactly the model used by FreeBSD, for example,
to maintain a separate "stable" branch along with the latest,
bleeding-edge HEAD of the CVS repository.
If the Emacs team agrees that such a maintenance Emacs 21.X
branch is ok to keep in the same CVS tree, you can use the
maintenance branch for bugfixes and/or features backported from
Emacs 22, as RefTeX or other Emacs 21 packages get updated.

Right. There are two different issues here, and I'm not sure if

be integration effort every time a new `source-drop' of RefTeX has

fine-grained file history we would have if the commits were done

integration effort, and lets us keep a better log of RefTeX
changes in the CVS tree of Emacs. It also means that RefTeX for
other Emacsen has to be maintained in *their* source tree though,
and risks a `fork' between the various RefTeX integration efforts
for all the different GNU Emacs versions and the other Emacsen.
I'm not sure if there is a good way to solve both problems.

We are not talking about maintenance, but about regular development
which involves new features. RefTeX is supposed to progress and stay
compatible with Emacs 21 and XEmacs at the same time.

No, because it would not be possible to install a new standalone

I don't see a big benefit in having the history directly in Emacs. If
you are interested in it, you can get it from the separate repository.

You'll have the history in Emacs' CVS repository. With an entry every
time a release of RefTeX is checked into the Emacs repository.

That depends if changes to RefTeX files in the Emacs repository are
allowed, which I would be in favor of. In that case we'd need some
way of transferring changes made in the Emacs repository into the
RefTeX repository; preferrably automatically. That's what the subject
of this message refers to.

I guess I'll chip in with how I manage to keep the development version
of ERC synced with that included with Emacs 22. Gnus does it slightly
different than I do, because they merge directly to Emacs 22, rather
than using an intermediary branch like I do.
I use GNU Arch to maintain ERC. Among the various branches are these:
erc--main--0 :: Where development happens
erc--rel--5.1 :: Where the currently previous major release (5.1) gets
updated when it is time to prepare a minor release.
erc--emacs--22 :: The branch which is used to sync to and from the
version in Emacs 22.
emacs--devo--0 :: The equivalent of CVS HEAD for Emacs in Arch, kept
in sync by Miles Bader.
* Preparation
When preparing the Emacs 22 version of ERC for the first time, I added
explicit Arch tags to all of the files which would be included with
Emacs 22. Namely: all .el files that don't depend on anything outside
of the Emacs source tree, NEWS (renamed etc/ERC-NEWS in Emacs 22),
ChangeLog, and the manual. This way, even if the files are in
different directories, Arch can sort them out.
I then set up a couple of scripts (in a scripts/ directory that only
exists in the erc--emacs--22 branch) that help me sync to and from the
Emacs 22 source tree.
common.defs:
===
# Common definitions for syncing ERC -*- Shell-script -*-
EMACS=~/proj/emacs/emacs
ETC=$EMACS/etc
LISP=$EMACS/lisp
MAN=$EMACS/man
===
sync-from-emacs:
===
#!/bin/bash
# Load common definitions
. scripts/common.defs
(cd $LISP/erc && find . -maxdepth 1 -mindepth 1 -type f -exec cp {} $OLDPWD \;)
cp $ETC/ERC-NEWS etc/
cp $MAN/erc.texi man/
rm -f *.elc
===
sync-to-emacs:
===
#!/bin/bash
# Load common definitions
. scripts/common.defs
(cd $LISP/erc && find . -maxdepth 1 -mindepth 1 -type f -exec cp {} $OLDPWD \;)
cp $ETC/ERC-NEWS etc/
cp $MAN/erc.texi man/
rm -f *.elc
===
* Syncing changes
When there are some changes that need to be propagated to Emacs 22, I
first check emacs--devo--0 to see if someone changed things on the
Emacs side, by running ./scripts/sync-from-emacs. If anything is
different than the current contents of erc--emacs--22, I immediately
check them in (to erc--emacs--22).
Then, I apply the necessary changes from erc--main--0. Once all of
the conflicts have been resolved, I check in the code and run
./scripts/sync-to-emacs. I then check to see whether Emacs still
compiles. Depending on how large the changes are, I may test them.
Then, if changes were made to files outside of lisp/erc in the Emacs
tree, I add log entries for them in their respective directories.
That done, I check the changes in to emacs--devo--0 with a brief log
entry.
* Closing thoughts on related subjects
I think it is unrealistic to expect that large, active projects which
are included with Emacs 22 use the Emacs source tree for their main
development area. It makes much more sense for such projects to just
merge in critical updates and new releases. It also makes rapid
development easier, because operations on the revision control system
of choice take significantly more time on the entire Emacs tree as
compared to just the files of the individual project.
I also think it is a very bad idea for Emacs developers to mandate
checking in files individually. It might make sense for work on the
core files in lisp/emacs-lisp/ or the top-level of lisp/, but a
significant percentage of changes made to the other lisp files involve
changing several files at once. Separating log entries for commit
messages begins to become a burden. For operations such as updating
an entire project, this would become very tedious (not to mention
unnecessary, because ChangeLog contains all the information that is
really needed).
With Arch, such changes are treated as a single change to the entire
project, rather than multiple separate changes to single files. There
is no possibility (however remote) of changes to several files being
only partially applied, as long as Arch is the only version control
system involved.

AFAIK changes to Gnus files in Emacs' repository will be transferred
automatically via Miles' Arch repositories to Gnus' stable branch.
I'm not sure how changes relevant to the trunk are moved there.

So you are updating ERC in Emacs not on a release-by-release basis,
but rather when some important changes need to be propagated? Do you
apply a tag in that case in order to identify the file revisions if
somebody has a bug report or support request referring to the ERC
version in Emacs or do you just use the files in Emacs directly for
testing and debugging?

Do you regularly synch from Emacs or just when you are about to synch
to Emacs?
My idea for RefTeX would have been that a synch from Emacs to RefTeX
is done regulary, but directly instead of using an intermediate
repository.

That reminds me: When you are synching from Emacs to ERC (and vice
versa) the ChangeLog file is probably handled the same way Lisp files
are. Because log entries of changes to RefTeX in Emacs currently end
up in lisp/ChangeLog we'd need a separate ChangeLog file for RefTeX
for this to work.

As Savannah supports Arch repositories now it should be no problem to
maintain RefTeX in such a repository. What I would be missing with
Arch would be something like PCL-CVS and the web interface like
Savannah provides it for CVS repositories.

Uh, I don't see why having CC mode in Emacs would make this easier:
the whole point of the uninstalled fixes is that they are fixes to a
comparatively _stable_ version fit for release with Emacs 22. The
HEAD of CC mode is _much_ less suited to be released with Emacs 22 if
I have understood things correctly.

I'm not sure which changes (to which trunk?) you have in mind here.
The section "Syncing" in texi/gnus-coding.texi [1] in the Gnus trunk
(maybe it would be useful to add this file to Emacs CVS in
emacs/admin/?) describes the process. Feel free to ask if something
is missing or unclear there.

If I understand Stefan correctly, it's possible to create a branch
with just the RefTeX relevant files. So it should be possible to "cvs
co -t reftex_devel ...", i.e. only check out RefTeX relevant files
from Emacs CVS. If not with this command, it should be simple to make
such a target in admin/reftex/Makefile nevertheless (cvs [...] co
emacs/admin/reftex/ && cd emacs/admin/reftex/ && make fetch-files).

A the changes would be done in the Emacs CVS directory layout, also
these ChangeLog files (lisp/ChangeLog, man/ChangeLog) should be used.
No problem with `C-x 4 a'.
I played a bit with the following[1] sketch of admin/reftex/Makefile.
Using grep-changelog we can build RefTeX-only ChangeLog files (some
entries are not extracted correctly, but this could be remediated by
re-writing the corresponding entries in the original ChangeLog files
(or improving grep-changelog?).

Arch is a distributed SCM, and it can keep track of what changes have
been merged. Michael mentioned that he keeps various Arch branches for
synchronizing the ERC tree with Emacs:
erc--main--0 :: Where development happens
erc--rel--5.1 :: Where the currently previous major release (5.1)
gets updated when it is time to prepare a minor release.
erc--emacs--22 :: The branch which is used to sync to and from the
version in Emacs 22.
Merging changesets from one Arch branch to another one is easy. Arch
keeps track of the changesets you have merged from erc--main--0 into
erc--emacs--22.

In distributed SCM's a "branch" is, effectively, a "repository". For
example, for my own Emacs stuff, I keep the following "branches" around,
with Mercurial (another distributed SCM):
emacs/gnu
emacs/keramida
Changes are automatically pulled into emacs/gnu, from a cron job, using
a conversion script which pulls over changesets from CVS.
I keep working in emacs/keramida, making my own changes.
Whenever I want to 'resync' with the official Emacs repository, I pull
changes from emacs/gnu into emacs/keramida and merge locally, inside the
emacs/keramida repository-branch.
After a merge, I can diff with emacs/gnu and post patches to the
official Emacs source tree.
My own suggestion, which pretty much matches what Michael and Miles do
with Arch, is that you *do* keep intermediate merge-branches in your own
repository, whatever the SCM you use will be :)

I have yet to find documentation of such a feature. The only thing
I've found was a usenet post warning not to branch selected files
only, because CVS gets confused when updating or commiting in a
directory containing branched and non-branched files. Such a mix
might not happen with the setup proposed by Stefan, however.

And what about standalone releases? Would those be shipped with
ChangeLog files for each directory? We'd probably have to clean those
files in the branch of any entries not related to RefTeX.

Okay, that would be another approach.
I still cannot say that I am too enthusiastic about maintaining a
package when its files are scattered throughout a larger repository.

If the Emacs team agrees that such a maintenance Emacs 21.X
branch is ok to keep in the same CVS tree, you can use the
maintenance branch for bugfixes and/or features backported from
Emacs 22, as RefTeX or other Emacs 21 packages get updated.
Making such branches is ok with me.

The
HEAD of CC mode is _much_ less suited to be released with Emacs 22 if
I have understood things correctly.
When packages are maintained inside Emacs, people work on development
somewhat differently, implementing improvements with an eye towards
releasing them in the next Emacs release.

Uh, reality check. The situation with RefTeX is that nobody works on
it any which way except Carsten, and he is passing on the buck because
he no longer has time for it.
So the current situation is that RefTeX is not maintained, whether in
Emacs or outside of it, and that is what we have to start with. Now
the question is where we can hope to get the most attention for it.
In the Emacs repository, we have a tex-mode.el that gets very little
attention from Emacs developers. Mainly Stefan Monnier if I am not
mistaken. If one takes a look at who did changes to RefTeX in the
past, it is very basically a one-man show, more so than tex-mode.el.
RefTeX's approach is an "all-around" one, similar to AUCTeX's. At the
current point of time, RefTeX can only be used for LaTeX, and there
are very few people actually writing LaTeX in Emacs without using
AUCTeX. Those that prefer using the minimal tex-mode.el are not
usually the kind of people that use comprehensive tools like RefTeX (I
seem to remember that Carsten did not know of anybody using RefTeX at
the current point of time with tex-mode.el or other LaTeX modes).
RefTeX even has its own section in the AUCTeX quick reference sheets,
and there are a few references to it in the AUCTeX manual.
Ultimately, I hope that the point will become mostly moot by AUCTeX
being folded into Emacs. However, I still think a separate repository
like with Gnus makes sense, and the time frame for folding AUCTeX into
Emacs will probably be still years because of copyright paper reasons
(we are progressing there, but not really fast).
It is my opinion that the chances of RefTeX getting more development
done on will be better with RefTeX in the AUCTeX repository rather
than Emacs. So I'd definitely prefer a solution where the Emacs CVS
contained mostly a variant of RefTeX intended for release with Emacs
only.
Having the RefTeX infrastructure scattered across the Emacs CVS
repository will rather get us fewer developers willing to actively
touch it than even the current situation.
I mean, let us just ask: are there any Emacs developers listening who
can imagine themselves working on RefTeX? If so, would they think
using the Emacs CVS more convenient for them than the AUCTeX
repository?
Of those who would consider working on RefTeX, how many have an
assignment and/or CVS write access for Emacs, and how many for AUCTeX?

I am not sure why that question is relevant. We may have a shortage
of people who would want to maintain RefTeX, but that isn't a matter
of where the repository is.
Given that RefTeX has a separate repository already, I don't think
there is any harm in moving it, as such. (I already said so.)
However, moving it into the AUCTeX repository creates a possible
specific risk. Namely, the risk that AUCTeX contributors who have not
signed papers might put changes into RefTeX also.

Are there any current contributors to AUCTeX who have not yet signed

It hasn't: Carsten has worked on it basically without version control
or at least version logs at home. He considered the history in the
Emacs ChangeLog to be much more relevant than what he got himself.

No, that risk does not exist. We don't give CVS access to AUCTeX
developers not having signed papers. The assignment problems of
AUCTeX only concern old code, and not all of it (for example,
preview-latex, a subsystem of AUCTeX, is completely covered).

No. It is only old contributors, and we covered all of the principal
ones. The rest may be a lot of work, but the actual amounts of code
concerned are not too extensive as far as I can see.

There is xtla-el (https://gna.org/projects/xtla-el), which is an Emacs
interface to GNU Arch. I haven't used it (yet), but people say it's quite

Yes. Of course, it's a priority to merge releases to Emacs 22.

No. I can get changes for any revision that I commit at any time, so
there isn't a need for making tags. I use DVC
(http://download.gna.org/dvc/) to easily fetch changes: it gives me a
listing of patches that I've committed, and I only need to hit "=" to
view the one at point in diff form.
I usually do debugging in the erc--main branch, because the versions
are consistent enough that problems should be replicable there. If
needed, I could easily just remove the (add-to-list 'load-path ...)
line for ERC from my config, and work in Emacs directly, calling
sync-from-emacs when I've fixed the problem (to propagate to
erc--emacs--22), and so on.

Usually I only do it when I'm about to sync to Emacs. I also do it
whenever I run "tla update" on Emacs 22 (about once a month), if I
notice that some ERC files were modified.

That would be trickier. I assumed RefTeX would be getting its own
subdirectory in lisp/. You might have to keep a separate ChangeLog
and manually copy over ChangeLog entries when syncing to Emacs 22.

I don't really know what PCL-CVS is used for, but DVC (link given
above) satisfies me. It really brings out Arch's potential.
As for a web interface, I set up one on my own webserver, and edited
Savannah's configuration for ERC to point to it. Link is:
http://www.mwolson.org/cgi-bin/archzoom/archzoom.cgi/erc@sv.gnu.org
For safety's sake (to keep from getting close to my disk space quota),
I have a cron job on my webserver that removes the generated
changesets and such once a week. This assumes that ArchZoom has
temp_dir = /home/mwolson/tmp.
remove-tmp:
===
#!/bin/sh

Xtla has now evolved into DVC. DVC is getting fairly stable, and
supports other distributed revision control systems (particularly bzr
and Mercurial) in addition to Arch.
URL: http://download.gna.org/dvc/
The Arch component of DVC is just as complete as the last release of
Xtla.

Additionally, I should add that I keep a checkout of each branch in
its own directory. For example: erc/emacs22 (erc--emacs--22),
erc/arch (erc--main--0), erc/arch-5.1 (erc--rel--5.1). This makes it
very easy to do sanity checks (diff -u against two directories) to
make sure that every desired change has been merged.

No, that risk does not exist. We don't give CVS access to AUCTeX
developers not having signed papers. The assignment problems of
AUCTeX only concern old code, and not all of it (for example,
preview-latex, a subsystem of AUCTeX, is completely covered).
Ok, I am satisfied on this score.

It hasn't: Carsten has worked on it basically without version control
or at least version logs at home. He considered the history in the
Emacs ChangeLog to be much more relevant than what he got himself.
In that case, I think this will be, to a certain extent, a step back.
But we can live with it.
So we can drop this topic.

Uh, we can live with what exactly?
> So we can drop this topic.
The topic was whether it would be ok to have Carsten Dominik pass on
maintenance of refTeX basically to the AUCTeX team and have RefTeX's
primary CVS moved as a module to AUCTeX CVS, while keeping the update
process of Emacs' builtin RefTeX as it currently is (namely refreshing
the CVS with stable changes and fixes while Emacs is in freeze).
While I tend to interpret your mail as you being ok with that
approach, I don't find that interpretation sufficiently unambiguous to
be sure.

Maintaining RefTeX in the AUXTeX repository,
as was proposed.

Thanks. I really think that this is the way best for future RefTeX
development.
Further discussion to auctex-devel. We will need to ask some savannah
hacker to make a copy of the Emacs CVS into an AUCTeX module, and then
we'll need to check in the additional files from Carsten.
And then we will have to fix refTeX to make it work with AUCTeX's
docTeX-mode...

Hi Ralf,
I moved the MH-E repository from SourceForge to Savannah a year or two
ago reluctantly, and it has simplified maintenance a lot by
eliminating the merge process, even though it was largely automated.
It was not a problem getting the requisite papers from the MH-E
developers.
While Emacs is not in pretest, it is not a problem to develop and
release your package at any time. We have our own version
(mh-version), our own tags (try cvs stat -v lisp/mh-e/mh-e.el), and I
recently added a :package-version keyword to defcustom so that you can
track the changes to your options in the various versions of your
package.
I would have preferred that a branch were created by the Emacs
developers once the code was frozen for the first pretest so that we
could continue to develop MH-E on the trunk. The rationale is that
there is a lot more development on the trunk than on the pretest
branch, and therefore merging from a branched pretest to the trunk is
a lot easier than vice-versa. A branch also protects the pretest from
unnecessary check-ins. But, until that happens, we can fairly easily
create a branch ourselves and merge back to the trunk once Emacs is
released.
In short, I'm much happier using the Emacs repository at Savannah.

Thanks very much for sharing your experience. Nevertheless, given
what you've written above I think we've made the right decision to
maintain RefTeX in a separate repository.
