Well creating a unison-doc package would be easy-- it only has two files, the 
HTML and PDF manuals.  But please tell me that for the source package I 
wouldn't then have to get the TeX source and compile it into HTML and PDF 
using the Hevea compiler, which would then require a package of its own-- I'm 
entirely uninterested in going down that road.

For just a docs package, can I get away with having no corresponding src 
package at all?

Thanks,
Andrew.
