Questions regarding TeX backend

[Daniel Johnson]

Hello all --

First, the background:

I am creating sheet music for a project that requires that titling and 
lyric text be set in Times (or a Times lookalike). Using lilypond 2.5.8, 
I was able to use the ptmr font when invoking lilypond -b tex.  However, 
since version 2.5.10 (possibly also 2.5.9) dvips is unable to locate the 
feta fonts, so in my Postscript output there are lots of Courier glyphs 
instead of clefs, noteheads, etc. (though the text fonts are correct; 
and all fonts look right in the DVI file).  I've tried manually invoking 
dvips with the arguments given in the documentation for lilypond-book 
but that doesn't help. Here's my invocation:

dvips -Ppdf -u+lilypond.map -u+ec-mftrace.map -q -t letter -o 
${LILYFILE}.ps ${LILYFILE}.dvi

I've tried using ptmr and friends using the postscript backend but 
lilypond complains that it can't find the corresponding Type 1 fonts for 
ptmr.  I've also tried installing the ptmr .pfb files via KDE's font 
manager; lilypond stopped complaining, but the font is still incorrect 
in the PS/PDF output (it's showing up as monospace).

Now, the questions:

1. Is the TeX backend broken? Are there any command-line options that 
fix the problem?
2. By what nomenclature does one select text fonts using the postscript 
backend? Where does lilypond (or pango?) look for these font files?  
Must these fonts be visible to TeX? Can anyone give a working example?

With regard to question 2, it seems to me that section 7.3.2 in the 
manual should probably be updated too, since font handling now seems to 
vary depending upon the backend.

Thanks in advance,
