Hypermail is a program that takes a file of mail messages in mailbox
format and generates a set of cross-referenced HTML documents. Each
file that is created represents a separate message in the mail archive
and contains links to other articles, so that the entire archive can be
browsed in a number of ways by following links. Archives generated by
Hypermail can be incrementally updated, and Hypermail is set by default
to only update archives when changes are detected.
