+TrueType and OpenType formats are supported).  Font series from light to ultra
+bold, and (faked) small caps and (faked) slanted shapes are supported, but not
+expert fonts.  The script will rename the fonts automatically (optional) or
+will otherwise expect the @file{.afm} files and the font files (in PostScript
+Type1 format) named in the Karl Berry scheme (e.g., @file{5bbr8a.pfb}).  After
+running the script, you should have a working font installation in your local
+TeX tree.")
