Readmail can read messages from yarn's news.dat file and from mail folders
such
as inbox. And it can output one or more selected messages as flat files, as
files in unix mailbox format, or as a soup packet.
Therefore you can use readmail, instead of the 3 or 4 other single yarn
utilities to:
o Convert from yarn folder to soup packet
o Convert from yarn folder to flat textfile
o Convert from yarn folder to mail file (and possibly re-import into yarn
to fix
problems, etc.).
Readmail has some memory limitations (will process only about 800 separate
messages), and is an interactive program (whereas the utilities tend to
process
files as batch type filters). But I thought this convenience was worth the
mention.
In general, I find the sheer number of different yarn helper utilities hard
to remember
(that is, what program does what with what options).
