installing complete generated directory trees

[Dan McMahill]

I have a program which as part of its build generates a large directory 
structure that is a couple of levels deep and has a couple of thousand 
ascii data files that the program may make use of at run time.

I'm wondering what the right way is to get this installed by automake. 
Also I'm debating including those generated files in the distfile to 
avoid one extra build time dependency (there is 1 extra tool needed to 
generate these files that users may or may not have installed) for users 
building from a distfile.

I guess I could use tar in an install-local: target but I didn't know if 
there was a supported way.  For the distfile, I didn't see any good way.

Thanks.
