* Use stdenv.mkDerivation instead of composableDerivation.
stdenv.mkDerivation is the current coding standard and is easier to
read (IMHO).
* Remove the 'parportSupport' flag because it doesn't do anything.
(Parallel port support is still enabled.)
* Remove unneeded --disable-dependency-tracking flag to ./configure; our
default builder does that already.
* Fix documentation build. But it is still disabled (by default),
because texLive is such a big dependency. There is always the man
page.
* Update 'meta' attributes
