Validation!  I see that I am not the only one who wants this.  I
believe that I posted similar requests earlier, but the response was
not overwhelming.  I would like this to be a CVS distributed item,
just like the other apps.  (Of course, the real solution would still
be to use gnats or something similar).  Anyway, you are free to
contribute to the FAQ that I have already started.  (I have written it 
using the linux-doc DTD, because docbook was difficult to find at the


P.S.  I have nailed down the first three of your items already (and

/usr/share/autoconf/acspecific.m4.  Are all of your autoconf files in 
/usr/lib/share/XXXX?  (Notice that my path had no "lib" in the
