Each message consists of two parts.  An "A" (ABSTRACT)
message which is a one screen description and summary of the
main message "B" (BASIC TEXT).  The "B" message contains, in
ASCII, the details of the topic in a much longer message,
usually no more than 10 screens (about 5 text pages).  If the
original "B" document is longer than 5 pages, it is split into
the appropriate number of "B" messages.  The purpose of the "A"
message is to give the reader some idea of the topic without
having to read or download the much longer "B" message.  At
present only ASCII text is being transmitted, so that figures,
maps, tables, and graphics are not included.  Generally the
figure cations and a brief description, where sensible, are
added to the text.  
     A goal for the future is a "C" (COMPLETE) message which
can contain everything..
     Each message has a header:

Obviously, not all categories are mutally exclusive.  For each
document, a main category is picked and contributory categories
are noted in the heading of messages if appropriate.  
This multiple category listing may be absent in the earlier messages.
