acincludedir -populating an m4/ subdirectory

[Guido Draheim]

It is great that aclocal/autoconf can now m4_include multiple
files from a local m4/-subdirectory. Yet, I was missing a tool
to populate it. A while back I just modified the standard
aclocal to do that - i.e. instead of --ouput=FILE using an
--output-dir=DIR. However, as far as I can see, the current
cvs aclocal.in was not extended as such. That's sad, especially
given how easy it is do add.

So, I did return to my earlier acinclude tool (which itself is
based on some very old aclocal version). Applying a similar
patch I am now symlinking it to be "acincludedir" which does
populate some project-local m4/ subdirectory with autoconf
macros from a site-local macro repository. It works similar
to the old acinclude. You can find the documentation at

http://ac-archive.sourceforge.net/doc/acincludedir.html

The source code is present in the download tarball of
the AC-archive. Which does now carry some more tools
that you might like. Please test and report any problems,
thank you,
