+ * automake.in (handle_source_transform): All dep_files are
+ relative to $(srcdir).
+ (handle_libraries): Ditto.
+ (scan_configure): Test for AC_PROG_INSTALL as well as
+ fp_PROG_INSTALL. Don't error here.
+ (seen_prog_install): Now global.
+ (scripts_installed): New global.
+ (handle_scripts): Set it.
+ Give error if appropriate install macro not seen.
+ (handle_subdirs): Ensure $seen_gettext before requiring
+ gettext-specific files.
+
+ From Jim Meyering:
+ * automake.in (handle_source_transform): Use \W when quoting
+ regexp. When blah_SOURCES not explicitly defined, still create
+ entry in %deps.
+ * depend.am ($(srcdir)/.deps/%.P): Don't use \< in regexp.
+ * subdirs.am (maintainer-clean-recursive): Now depends on
+ $(CONFIG_HEADER) and Makefile.
+
+ * automake.in (handle_source_transform): Skip macro references.

* automake.in (handle_texinfo): Include "rm" when deleting files.
New in 0.29:
-* Bug fixes
+* Many bug fixes
* More sophisticated configure.in scanning; now understands ALLOCA and
LIBOBJS directly, handles AC_CONFIG_HEADER more precisely, etc.
* TEXINFOS and MANS now obsolete; use info_TEXINFOS and man_MANS instead.
* CONFIG_HEADER variable now obsolete
* Can handle multiple Texinfo sources
* Allow hierarchies deeper than 2. From Gord Matzigkeit.
+* HEADERS variable no longer needed; now can put .h files directly into
+ foo_SOURCES variable.
\f
New in 0.28:
* Added --gnu and --gnits options
Handle MAINT_CHARSET. Use recode in dist target. Handle dist-zoo and
dist-zip.
+If AC_PATH_X given, add extra stuff to generated Makefile.in.
+
Add support for html via an option. Use texi2html. Use
"html_TEXINFOS", and htmldir = .../html. Include html files in
distribution. Also allow "html_DATA", for raw .html files.
a potential bug: configure puts "blah.o" into LIBOBJS, thus implying
these files can't be de-ansified. Not a problem?
+consider automatically adding -I$(srcdir) to INCLUDES.
+
In general most .am files should be merged into automake. For
instance all the "clean" targets could be merged by keeping lists of
things to be removed. This would be a lot nicer looking. Note that
'maintainer-clean' should "rm -rf .deps". Ditto distclean
Should look for clean-local targets in Makefile.am.

Think about writing a small tool to guess what the local Makefile.am
should look like.

Should libexec programs have the name transform done on them?

-If your @file{configure.in} uses @samp{AC_CONFIG_HEADER}, then in each
-directory you should define the @samp{CONFIG_HEADER} variable to hold
-the name of the header.

-For instance, in cpio's @file{src/Makefile.am}, we see:
-
-@example
-CONFIG_HEADER = ../config.h
