[tex-live] documentation of arydshln

[Karl Berry]

    running the documentation file of arydshln.sty requires
    the dtx file, which is read by the arydshln-man.tex.
    But this file cannot be found by tex, it is in the
    source directory.

I know the problem, but that is simply the way TL has always been
arranged (since long before I was involved) -- the dtx/ins have always
been put in the source/ subtree.

However, I'm not sure if it really gains anything to have the dtx/ins
under source; perhaps it would be better for them to be in the
doc/package directory, which would keep everything together.  I've
thought about that, but it's quite a big change, so I procrastinate ...

I'd rather not treat arydshln differently than every other package in
this regard.  I expect there are plenty of other packages with a similar
setup.

Why were you rerunning the doc, anyway?  (Just wondering.)
