Yeah - I really hate having to have multiple projects. The example and
doc war are not projects, they are part of the website in Maven terms
- we just don't want to do things in xdoc or apt. Feels that it should
still be entirely doable as a single project.

I think we should try for an atomic project; see if that works. Only
if we can't make that fit should we go the triple project route.

I think this is the first decision - is there any value in keeping the
tld generation. It's not as if we've been building and distributing
taglibs for different spec versions; the RM has always chosen one.

The simpler we keep the build, the more we can maintain with less
effort. While powerful, I think the build system's complexity has been
one factor in lack of energy to do anything.

Course - the other part is the general lack of energy in JSP :)

Yeah, didn't look too hard, just haven't done it since m1.

Artistic licensed - so made me wince and I looked for others :)
