   BUGS
     The -h switch can only hide header lines that trn knows about.

     The '-' command doesn't cross newsgroup boundaries, and only undoes the
     last article selection.

     If you edit your .newsrc while trn is running, trn will happily wipe out
     your changes when it decides to write out the .newsrc file.

     Marking of duplicate articles as read in cross-referenced newsgroups
     will not work unless the Xref patch is installed in inews.

     If you get carried away with % or escape substitutions, you can overflow
     buffers.

   DIAGNOSTICS
     Generally self-documenting, as they say.
