Honestly, I'm not sure; I was trying to implement the easiest possible thing
that will work for TDS-compatible installations.
The procedure otftotfm uses is relatively simple:
1. Look for a writable TEXMF.
2. Put files under that TEXMF as follows:
Type 1 TEXMF/fonts/type1/VENDOR/TYPEFACE/
3. Update TEXMF/ls-R as appropriate.
This procedure was relatively easy to write and, much more importantly, easy to
explain in the manual.
Last night I coded up a "hack" for TDS 1.1/recent teTeX installations, namely to
use kpathsea to look for an 'ENCFONTS' variable. If that variable exists, then
otftotfm assumes TDS 1.1, and changes the locations of encoding and psfonts.map
files as follows:
I suppose that the "right thing" would be to use kpathsea to expand the relevant
search paths for each type of file, and put the files in the first writable
directories found. But I'm loath to code this up unless it's strictly necessary.
* This more complex procedure would be harder to explain in the manual; I feel
like I'd start getting confused bug reports.
* The search paths might contain directories not under any TEXMF; it's not
immediately clear how and when to update ls-R.
* The kpathsea search paths don't tell you whether to append VENDOR/ or
VENDOR/TYPEFACE/ or nothing.
* Plus coding it would be kind of a pain in the ass.
* If you have a special installation you can always turn off automatic mode and
install the files wherever you want.
Does this make sense, or should I just bite the bullet?
