[twg-tds] texmf/scripts and texmf/fonts/lig

[Karl Berry]

Here is a first draft of adding the proposed texmf/scripts and
texmf/fonts/lig directories to the TDS document.  I'm leaving out a
number of editorial changes from the diff here, but I'll attach the full
source and DVI output.

I'm not especially happy with my text, but at least it's somewhere to
start.  Please give specific suggestions :).

Thanks,
k

! The TDS also reserves the names \path|enc|, \path|lig|, and \path|map|
! for font encoding, ligature, and mapping files, respectively.  These
! directories are structured according to package names (e.g.,
! \path|dvips|, \path|afm2pl|), possibly with subdirectories.  Each of
! these file types is intended to be searched along a single
! recursively-searched path.  The names of the actual files must be unique
! within the entire tree, as usual.
! 
! For examples, the Fontname collection and Dvips package both have a
! number of instances of \path|enc| and \path|map| types.  The
! \path|afm2pl| program uses \path|lig| files.
