Ehwhoops.

OK.  The code will (1) look under "other text files", then if not found, (2) 
look in PREFIX/share/lcdf-typetools ($pkgdatadir).

The makefiles will not, however, install glyphlist.txt in a TDS.  You'll have to 
do that by hand.

No.  lcdf-typetools installs 7t.enc in PREFIX/share/lcdf-typetools, but just as 
information.

OK.  I had been setting it explicitly to argv[0]; will anything go wrong for 
existing installations if I just switch to lcdf-typetools?  Also, lcdf-typetools 
contains a dash, which leads to kpathsea lookup on environment variables that 
contain dashes.  That'll surely cause a problem for someone.  I suggest 
"lcdftools" instead, which is what otftotfm already uses for vendor strings.

That's right, I wouldn't.  The lcdf glyphlist is different from Adobe's in 
several ways.

One of them is actually worth some thought.  In Adobe glyphlist, the name "phi" 
maps to a "loopy" phi, while "phi1" maps to a "straight" phi.  In TeX practice, 
as codified in the encoding files, this is reversed: "phi" is straight, "phi1" 
is loopy.  My glyphlist.txt recodes to match the TeX practice, but this feels a 
little iffy.

I will release 2.34 with these changes if you approve.

Eddie
