That's right. As long as we distribute the Makefile.in (which is
derived from the automakejar processing).

And normally the first step for the build developer would be
different to because it would just be:

  $ autoconf

It isn't at the moment because we have an automake autoconf.

Well, it's useful to have automakejar try to make a Makefile.in by
default because sometimes one doesn't use autoconf. I've been
thinking that automakejar should scan the current directory for the
configure files and output to Makefile.in if it finds them.

Interesting point. I don't particularly like the idea of a prefix or
a block construct... the real point is that these things are NOT make
targets, they are automakejar targets, but they are still targets, you
can even add dependancies like this:

texinfo-doclet.jar: some-dependancy  another-dependancy

As it stands the automakejar target is quite useful because it is a
bunch opf variables and syntactically won't have any effect under

It's just my standard (c). I'm happy to assign automakejar to the FSF
if they're interested in having it.
