	* redhat/dejagnu.spec: Install all the doc formats.
	* Clean.tcl: Also nuke all Emacs backup files.
	* Makefile.am: Fix dependencies on tarball target. Add new target
	to build Debian packages. Add $(includedir) to install-data-local
	target so dejagnu.h gets installed in the right place.
	* doc/Makefile.am: Make all paths absolute, cause some versions of
	the db2* tools are braindead.
	* doc/overview.sgml: Update version numbers and log.
	* doc/user.sgml: Add mention of dejagnu.h header file.
	* doc/ref.sgml: Add chapter on dejagnu.h header file for unit
	testing.
	* config/default.exp: New file for default config settings for
	simple native testsuites that don't need anything else.
	* lib/dejagnu.exp: Add $text\r\n to all strings, to make sure we
	only get one line at a time.

	cases.

	case.
	* testsuite/libdejagnu/Makefile.in: Generated.
	* testsuite/Makefile.am: Add libdejagnu to SUBDIRS. Replace the
	site.exp rule, cause we don't want the $tool setting, so we run
	all the test suites. Don't pass the tool name for "make check".
	* configure.in: Add testsuite/libdejagnu/Makefile to AC_OUTPUT.
