 One of the aims while creating the font was its internal consistency.
 For example, accented glyphs shouldn't differ too much from unaccented

 ...and an alias called "univga" is added, so you can say e.g.:

+In most applications' font pickers, the font is just "VGA".

 Also 3 varieties of the font are installed for use with
 the Linux console: AsianCyr-vga-8x16, WinCyr-vga-8x16, and
 UniCyrX-vga-8x16. They can be used in /etc/rc.d/rc.font, but won't
 show up in the setconsolefont menu.

+By default, the BDF (old style X bitmap), PSF (Linux console), and
+OTB (new style Pango/Harfbuzz bitmap) fonts are installed. If you for
+some reason need it, you can also install the PCF (portable compiled
+X font) version, with PCF=yes in the environment. You can also set
+BDF=no, PSF=no, and/or OTB=no, if you want to omit one or more of
+these font types. Setting all 4 variables to "no" is an error, though.
