-+If compiled with <emphasis>--enable-nntp</emphasis> option, Mutt can
-+read news from news server via NNTP. You can open a newsgroup with
-+function ``change-newsgroup'' (default: ``i''). Default news server
-+can be obtained from <literal>$NNTPSERVER</literal> environment
-+variable or from <literal>/etc/nntpserver</literal> file. Like other
-+news readers, info about subscribed newsgroups is saved in file by
-+<link linkend="newsrc">$newsrc</link> variable. The variable <link
-+linkend="news-cache-dir">$news_cache_dir</link> can be used to point
-+to a directory. Mutt will create a hierarchy of subdirectories named
-+like the account and newsgroup the cache is for. Also the hierarchy
-+is used to store header cache if Mutt was compiled with <link
-+linkend="header-caching">header cache</link> support.

++<para>
++If compiled with <emphasis>--enable-nntp</emphasis> option, Mutt can
++read news from news server via NNTP. You can open a newsgroup with
++function ``change-newsgroup'' (default: ``i''). Default news server
++can be obtained from <literal>$NNTPSERVER</literal> environment
++variable or from <literal>/etc/nntpserver</literal> file. Like other
++news readers, info about subscribed newsgroups is saved in file by
++<link linkend="newsrc">$newsrc</link> variable. The variable <link
++linkend="news-cache-dir">$news_cache_dir</link> can be used to point
++to a directory. Mutt will create a hierarchy of subdirectories named
++like the account and newsgroup the cache is for. Also the hierarchy
++is used to store header cache if Mutt was compiled with <link
++linkend="header-caching">header cache</link> support.
