Anyone know how to install fonts in Ångström/E17?

I can't figure out how to add new fonts to Koen's Ångström/E17 Demo.
I'm trying to port an X Windows application that uses a lot of fonts
and I need to know:

1. What font file formats are acceptable to Ångström/E17?
2. Where should I put them?
3. How do to load them into the operating system?

Any help would be greatly appreciated!


Here are things I have tried:

Calling XGetFontPath returns one font path:
Font path 0 = built-ins

Calling XListFonts returns the following four fonts:
font: -misc-fixed-medium-r-semicondensed--13-100-100-100-c-60-
font: -misc-fixed-medium-r-semicondensed--13-120-75-75-c-60-iso8859-1
font: -misc-fixed-medium-r-semicondensed--13-120-75-75-c-0-iso8859-1
font: -misc-fixed-medium-r-semicondensed--0-0-75-75-c-0-iso8859-1

Trying to install my own font directory (which has fonts.dir and has
777 permissions) gives me:
# xset fp+ fonts
xset: bad font path element (#60), possible causes are:
    Directory does not exist or has wrong permissions
    Directory missing fonts.dir
    Incorrect font server address or syntax

Hooray! I was able to load the fonts I needed using the 24 August
version of Koen's Ångström Demo. "xset" still doesn't work, but I was
able to substitute my own directory for /usr/share/fonts/misc,
retaining the cursor and 6x13 fonts to keep Ångström and xterm happy.
If anyone has a similar problem and needs more detail, please respond
