Roman numerals in figured bass; also, TEXMF and TEXMFCNF behavior

[Tommaso Toffoli]

 Lilypond is wonderful, and its "body plan" is just right. Thanks.
I have two questions.

1. Lilypond has limited support for figured bass in the traditional
form of columns of digits indicating intervals relative to the bass note.
Today, for both pedagogical and practical reasons, it is common
to esplicitly give, besides those numbers, a Roman numeral
(sometimes in upper or lower case for, resepctively, major and minor)
indicating the chord root, such as

                 7       6
I       V       V       V4

This kind of figured bass, appearing below the staff, is distinct from the so
called "chord notation" such as

Fdim    F7      Cmin

etc. Is there a way in lilypond to notate these Roman
numerals in the  figured bass?


2. I use the kpathsea method of organizing TeX fonts. Specifically, beside the
system texmf tree in /usr/share I use a standard-structure texmf tree for the
user, called ~/.texmf, where I store user-defined fonts.

When I installed lilypond I couldn't get its fonts to appear until I ran the
lilypond.sh script in /etc/profile.d. After that lilypond worked right,
but my user fonts had become unaccessible. To get them back,
I had to do some searching. I finally changed the lilypond-generated export

  echo $TEMF
 
{/usr/share/lilypond/1.6.6,{!!/home/tt/texmf,!!/usr/local/share/texmf,!!/usr/share/texmf}}

 to

  echo $TEXMF
  
{/usr/share/lilypond/1.6.6,{!!/home/tt/.texmf,!!/usr/local/share/texmf,!!/usr/share/texmf}}

 (note the change /home/tt/texmf --> /home/tt/.texmf). I do not understand
this TEXMF story and its stepping over TEXMFCNF. (By the way, when is the
script lilypond.sh automatically executed if I leave it in /etc/profile.d?)

Do you have any suggestions how to do this right, and can you give the
installer a few more words of explanations? I'm afraid many potential
users may be turned off by this first difficulty and never come back.

Many many thanks.
