* Debian changes to Emacs

** version indicates that the Debian copy of Emacs has been
modified by Debian.

** Added new browse-url.el code.

Fixes support for mozilla, adds support for galeon, and defaults to
free browsers when available, rather than just trying netscape.

** added upstream patch for iso-acc.el accent bug.

** debian-emacs-flavor is a global variable bound to 'emacs21.

** The -i icon is the Emacs GNU.

** Some documentation references to /usr/local/ have been changed to /usr.

** Extra architectures are supported.

Support for the Debian/GNU/Linux ia64, and mipsel architectures has
been added.  A minor nocombreloc patch has been added.

** Emacs has been modified to run debian-startup during the startup
process unless site-run-file is false.

** /usr/share/info/emacs-21 has been added to
Info-default-directory-list to reflect the install location of the
info files.  This location allows multiple emacsen to coexist on the
same Debian system.

** mail-from-style changed from 'angles to 'system-default by default.

** The default for message-sendmail-f-is-evil has been changed to t.

This is correct for Debian systems where we know the MTA should be
trusted.

** The detection of the program "mail" has been enhanced.

We have added CONF_MAIL_PROGRAM_NAME to configure.in and use it in
fakemail.c.  Either via this variable, or via a #define in an arch
specific file, we now insist that this var be defined, and abort
compilation otherwise.  We use #error, which is probably not portable,
so we need a better solution long term.  This fix repairs a nasty bug
where on sparc-debian-linux-gnu at least, MAIL_PROGRAM_NAME pointed to
/bin/mail, which didn't exist, and fakemail failed silently, losing
mail.  In the long run, though, fakemail should be fixed to find the
mail program at runtime, and do something smarter if/when detection
fails.

** The location of the mail spool has been centralized.

[ This modification is currently only available in the Debian source,
  but the upstream authors and I are in the process of working out the
  appropriate upstream patch.

  Please do *NOT* use mail-spool-directory in any public code until
  and unless this variable makes it into the upstream source. ]

Determination of the location of the mail spool has now been
centralized.  There is a new lisp-level variable mail-spool-directory
that should always contain the location of the mail spool (normally a
directory like /usr/spool/mail).

There is a related configure option --with-mail-spool-directory that
allows you to override the default mail spool location detected, if
any, at configure time.  The proper setting for a particular
architecture may also be set in src/s/*.h with
SYSTEM_MAIL_SPOOL_DIRECTORY, but note that --with-mail-spool-directory
always takes precedence.

At the C level, the mail spool directory is available from
lib-src/mailspool.h which provides a MAIL_SPOOL_DIRECTORY definition.

nnmail, rmail, and movemail have all been modified to respect this new
arrangement.

** Mailbox locking improved and brought into line with Debian policy.

[ This modification is currently only available in the Debian source,
  but the upstream authors and I are in the process of working out the
  appropriate upstream patch. ]

Configure now looks for liblockfile before libmail (liblockfile is a
free software replacement for libmail).  Either library, if found, is
propagated to the movemail (lib-src) Makefile through the
MOVEMAIL_LOCK_LIBS variable.

Also MAIL_USE_FLOCK is disabled since it is wrong for a Debian system.

** #defines have been added to arrange for Emacs to use memset,
memcmp, and memmove instead of bzero, bcmp, and bcopy.

** HAVE_STDLIB_H checks have been added in a few places where they
were needed (in lib-src).

** The build process was modified to accomodate Debian's packaging
system.  Emacs has to be able to install into a directory that will
not be the eventual run directory without embedding the install
directory in any of the resulting files.
