Escm is a text file processor that expands embedded Scheme expressions in the input file. Unlike other text-embedded language processors, escm does not depend on a particular Scheme implementation---you can use your favorite Scheme.
The rfc2xml utility takes an RFC or Internet-Draft in text format and generates the xml format, reversing the xml2rfc (xml.resource.org) process. troff2xml and rfc2html have also been included.
