-Obfuscates fonts by deleting data that is not necessary for their use in web
-browsers. They should still work via \@font-face, but are a bit harder to
-install and use in other applications.
-The generated font will be invalid, so there are no guarantees of correct
-operation - be careful to test it with all current and future browsers that
-you want it to work in.
-
-Usage:
-  $0 [options] [inputfile.ttf] [outputfile.ttf]
-
-Options:
-  --verbose, -v         print various details about the font
-  At least one of the following is required:
-  --all                 activate all of the options below
-  --names               strip font name strings
-  --post                strip PostScript glyph names
