[tlbuild] LuaMetaTeX for TeX Live

[Mojca Miklavec]

Dear Norbert, Karl and others,

Quick question. How can I start experimenting with adding a new tool
to the existing build scripts?

Given that the subdirs are never explicitly listed, it looks like all
the subdirectories should be automatically discovered.

But on one machine I'm getting:

$ ./reautoconf
: not foundf: 22: ./reautoconf:
: bad variable namenset: CDPATH

and the other one (autoreconf-2.71 under MinGW on Windows) reports:

configure.ac:17: the top level
configure.ac:23: warning: The macro `AC_FOREACH' is obsolete.
configure.ac:23: You should run autoupdate.

and all the support for individual folders is gone after running ./reautoconf:

I think I have older versions of autoconf installed, but I need to
figure out how to pick an older version when regenerating the files.

(In any case it would be nice if the code was future-proof and if it
at some point in the future worked with autotools 2.71 as well.)
