NAME

       nnspew - subject database manager (nn)

SYNOPSIS

       nnspew

DESCRIPTION

       nnspew  builds  a sorted database of all available subjects in the nn article database for
       fast access via the nngrab utility.

       nnspew should be activated regularly to rebuild the subject database, e.g. by  cron.   For
       example:
          2 6,9,12,15,18,21 * * *  root /bin/nice /usr/lib/nn/nnspew

       Cross posted articles are only represented in the database once, and identical subjects in
       each group are merged into one to use a minimum of disk space.  This saves  about  50%  of
       the disk space otherwise required.

FILES

       $db/subjects   subject database

SEE ALSO

       nn(1), nngrab(1), egrep(1)

NOTES

       nngrap will use the subject database generated by nnspew independent of its age.  Thus, if
       you stop running nnspew, remember to remove the subjects file as well.

BUGS

       nnmaster should automatically append new articles to the subject database to keep  it  up-
       to-date, and thus require less frequent rebuilding using nnspew.
