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.
