+bitmapfont2ttf (convert bitmap BDF fonts to vector TTF)
+
+bitmapfont2ttf is a fontforge Python script which autotraces the glyphs
+in a bitmap font and converts it to a vector (outline) TrueType font.
+The resulting font retains its "pixelated" look when scaled up to any
+size.
+
+bitmapfont2ttf is a bit picky about the BDF fonts it will accept as
+input.  This build includes a patch that allows it to work with fonts
+produced by psf2bdf (from psftools). The patch is applied by default,
+but you can export PRISTINE=yes in the environment if you really don't
+want it.
+
+If you're trying to convert a PCF font, use pcf2bdf to turn it into a
+BDF first.
+
+If you're looking for exact-autotrace, it's included in this build.

+# Line up the first '|' above the ':' following the base package name, and
