Hello, There is some important change incoming in the organization of the code, mainly in the tp directory (and the name of the directory will amso probably change) to correspond better to the fact that there is now both a Perl and a C implementation of texi2any (though the Perl implementation is complete, while the C implementation is not).
If you follow the development tree, there will be leftovers, for now in tp/Texinfo/XS mainly (configure, TestXS.la...) , and probably more to come. Also you may need to rerun autogen.sh. -- Pat
