MuseSig is an email signature generator. The script takes an ID file (your contact information) and combines it with a quote taken from a local collection of quotes to produce a new signature file. Command line options allow selection of output file, the format to use (one of two types), and various other options. Quote files are plain text and new quotes can be added just by adding a new file to the quote directories.
