missing info in the models tarballs.

You need this info to build them, unless you are lucky..

They are designed to be unpacked in the gnucap core root.  
(where src, modelgen, COPYING, and those files are)  so plugins 
is one of those.  All of them will create plugins, so if you 
unpack them all in the same place, you will get subdirs in 
plugins.

If you unpack them anywhere else, you need to edit the 
file "Make2".  Change the line GNUCAP_INCLUDE to identify where 
the gnucap include files are.

Obviously I do not intend to leave it this way.  Obviously, the 
correct way is not obvious!

More info,hopefully a discussion, will follow.  I am treading 
new ground here.

To the autoconf lovers ...  If these files use autoconf, it 
becomes a run time dependency for gnucap.  That is not 
acceptable.  Plugin source is considered to be user data.
