OVERVIEW.FMT (5)

NAME
     overview.fmt - format of news overview database

DESCRIPTION
     The file <config$_PATH_SCHEMA> specifies the  organization  of  the  news
     overview  database.   Blank  lines and lines beginning with a number sign
     (``#'') are ignored.  The order of lines in this file  is  important;  it
     determines the order in which the fields will appear in the database.

     Most lines will consist of an article header name, optionally followed by
     a colon.  A trailing set of lines can have the word ``full'' appear after
     the colon; this indicates that the header should appear as  well  as  its
     value.

     If this file is changed, it is usually necessary to rebuild the  existing
     overview   database  using  expireover(8)   after  removing  all  existing
     overview files.

     The default file, show below, is compatible with Geoff Collyer's  ``nov''
     package:
