NOTE: This was the HISTORIC changelog-type document actually included
in the head of the AUB script. It was getting too bulky so I decided
to move it to a separate file. All new changes are kept in ChangeLog
which is generated from the CVS logs.

     v2.0.6 6/97        blong@fiction.net
                        added @kill_subj, a list of regex used for a
                        simple killfiling based on subjects.  Hardcoded,
                        default is to kill articles with multiple
                        exclamation points and .htm
                        also, removed dependency on sys/socket.ph, just
                        defined the values in this file

                        high number of canceled spam in the binary
                        groups)
     v2.0.8 5/98        blong@fiction.net
                        Fixed bug in handling of unresolved articles,

                        also, handles articles that only specify a hint
                        in the subject, and no piece information

----------------------------------------------------------------------
v2.1 -- Nov01 avinash:
 -- Removed most ` ` system() commands - major reduction in CPU load
    - instead of SUM use File::Compare()
    - instead of CAT for nntpserver, just read that file
    - instead of MV, use move() from File::Copy
    - $ECHO still being used, must exist in $PATH
 -- ONLYrecognize keyword added, reject files not with listed suffix
 -- SAMple keyword added, specify maximum number of articles to load
 -- duplicate file names are renamed without changing file extension
 -- summary statistics (number of files, rate of extracting) now provided
 -- catchup (-c) now resets aubrc - unresolved article numbers removed too
 -- Many minor updates:
    - connect_tcp() - no need to compute ouraddr for socket connection
    - last_article_seen was not being updated
    - move all aub config, rc, lock, etc files to $AUBHOME folder
    - work under Windows NT also
 -- socket.ph no longer needed, just use Socket perl module
