feature request: per-project settings

[Tom Tromey]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

This isn't a bug report but rather a feature request.

It would be convenient for me (and, I imagine, many others) if Emacs
supported per-project settings.

What I picture is something like `dirvars.el' (posted once upon a time
to gnu.emacs.sources), plus some extra code to provide easy
persistence of certain settings.

Ideally it would be possible for some settings to be specified by the
project, and others (still per-project) by the user.

As an example, indentation settings should be settable per-project by
the project itself.  This could be done by having some settings stored
in a file in the cvs repository; Emacs would automatically be aware of
these settings when opening a file in that project.

An example of per-user (non-shared) settings would be compilation
commands.  Right now I prime the cache of compilation commands in my
.emacs.  It would be more convenient for me if Emacs automatically
remembered compilation commands on a per-project basis.

gdb invocations could also be remembered this way.  (Ideally
breakpoints and the like would also persist, but just remembering the
gdb command-line automatically would be a good start.)
