What is the editor used for writing RFC text files?

Question

I am just wondering how much effort is required to write a text file like that with page numbers, table of contents, headers, footers etc. Is there any editor or some thing like TeX that is used for writing the RFC documents?

Answer 1

According to RFC 2223:

Most of the RFCs are processed by the RFC Editor with the unix "nroff" program using a very simple set of the formatting commands (or "requests") from the "ms" macro package (see the Appendix).

There is an RFC that details how they can be written using Microsoft Word: RFC 3285: Using Microsoft Word to create Internet Drafts and RFCs :-)
