Slrnpull pulls a small newsfeed, from an NNTP server, to a local news spool directory. The news spool can be used by news readers (such as slrn), which can read a local news spool without an NNTP server.
In combination with the slrn news reader, slrnpull can provide true offline news reading. You can tell slrnpull to download headers only, mark interesting ones for download with slrn and fetch those article bodies during the next run of slrnpull.
Slrnpull also has the ability to killfile articles so that they will not be downloaded from the server.
