(installed_h_files): Put in alphabetical order.
Remove duplicate entries for markers.h and unif.h.
(c_files): Remove duplicate entries for markers.c.
(ancillary): Renamed from anillery; all uses changed. Remove
PLUGIN; it's a directory, and needs special treatment in dist-dir.
Remove all the ../doc/* files; doc/Makefile.in handles that.
snapshots. Other changes in subdirectories.
* Makefile.in (dist): Rewritten --- the old target was out of
date, dependent on files that we don't have, and relied on GNU
tar. The new target is simpler.
(VERSION, srcdir, dist_dirs): New variables.
(DISTFILES): Renamed from localfiles. Added GUILE-VERSION and
TODO.
(localtreats): Variable removed. We don't have this file.
(info): cd to doc and make info there; don't make info in every
${subdir}; those Makefiles don't know what to do.
(distname, distdir, treats, announcefile): Variables removed.
(manifest-file): Target removed.
(dist-dir): New target, responsible for distributable files in
this directory.
(GZIP, GZIP_EXT, TAR_VERBOSE, DIST_NAME): New variables,
controlling the 'dist' target.
* configure.in: Substitute GUILE-VERSION into the top-level
Makefile. Build doc/Makefile from doc/Makefile.in.
