Data.MBox.String

Description

Reads and writes mboxrd files as per http://www.qmail.org/man/man5/mbox.html.

This parser is written to be a streaming parser. Given a lazy source of data and a streaming consumer, you should be able to analyze arbitrary mbox files in constant space.

Synopsis

parseDateHeader :: String -> Maybe UTCTime
showMessage :: Message -> String
