The AsciiGlyphs package provides a command to print large ASCII glyphs in an HTML fragment based on a <pre>...</pre:> element. The shape of the glyphs was inspired by the challenge response used by Fossil to let anonymous users to log into a repository. The glyph set was extended to support the whole English alphabet and some punctuation characters. The string to be represented has to be made of pure 7-bit ASCII characters. The package also runs standalone outside of mod_rivet
