++If compiled with <emphasis>--enable-nntp</emphasis> option, Mutt can
++read news from newsserver via NNTP. You can open a newsgroup with
++function ``change-newsgroup'' (default: ``i''). Default newsserver
++can be obtained from <emphasis>NNTPSERVER</emphasis> environment
++variable. Like other news readers, info about subscribed newsgroups
++is saved in file by <link linkend="newsrc">$newsrc</link>
++variable. Article headers are cached and can be loaded from file when
++newsgroup entered instead loading from newsserver.
