To quote from the author, Brandon Long: This program is based on the program in Appendix A of rfc1896. It does as much as I can think of to convert text/enriched to text/html (since there are so many viewers for text/html). It is a hack. It is not perfect, and the html it generates is far from perfect. I've tried to follow HTML v3.2, but its still not great. Usage: Pass it the text/enriched body of a message on stdin, and it will put the text/html version on stdout. To make mutt display text/enriched, put this in your .mailcap file: # enriched.sh converts text/enriched to text/html and then uses lynx to display text/enriched; ${PREFIX}/bin/enriched2html | lynx -dump -stdin ; copiousoutput
