XVAXNOTES-TO-NEWS V2.2
X
XBasically works the same way, but it can `5Boptionally`5D consume files sent
V via
Xinternet mail.  It ignores the headers.  It also is more robust in the face
V of
Xsome of the vagaries I've seen in the output of NOTES EXTRACT/UNSEEN.
X
XI'm currently using it to gateway the ISVNET notes files into newsgroups and
V it
Xworks great for that application.
X
XIf you have any questions contact me.
X
XIf you spot any bugs or make fixes, be a sport and let me know so I can keep
Xthings up to date.

X         such as EXTRACT/ALL/UNSEEN XYZ.NOTES-DATA
X         into a file suitable for usenet format news processing.
X         e.g. by ANU-NEWS using a command such as
X         $ NEWS/NOSCREEN ADD FILE/NETFEED XYZ.NEWS-DATA

XAuthor: Dick Munroe <[e-mail]>
XVersion: 2.0
X`09 Rig this thing to be able to deal with messages containing notes
X`09 messages.
X
XVersion: 2.1
X`09 Apparently Notes doesn't consider blank lines trailing a note to be
X`09 part of the note.
X
XVersion: 2.2
X`09 Occasionally Notes OVERcounts the size of a note as well.  Rig the code
X`09 to check for this case and scan for the next art header.  This may
X`09 occasionally wind up with a bogus note entered (for example, when notes
X`09 are posted to notes AND the count gets off) but there won't be THAT
X`09 many of these.
X
X`09 Occaisionally Notes puts a blank line in BEFORE the header which
X`09 specifies the source of the notes.  Skip blank lines before getting to
X`09 the sources of the notes.
X
X`09 Occaisionally Notes breaks the topic header following the note title.
X`09 I'm going to take advantage of the fact that all item header lines
X`09 should be at LEAST 80 characters in length to fix this.
