+The *.ttf and COPYING files in this directory were copied from the X.org

+
+There are three typefaces: sans (s), serif (r) and monospaced (m). Each
+typeface has four fonts: regular (r) and bold (b), and roman and italic (i).
+For example, luxisb.ttf is sans, bold and roman.

+The *.ttx files in this directory were generated from the *.ttf files
