-This command allows to test if a feature has been compiled in, before

-function or a variable.
+These command allows to test if a variable, function or certain feature
+is available or not respectively, before actually executing the command.
+<tt/ifdef/ (short for ``if defined) handles commands if upon
+availability while <tt/ifndef/ (short for ``if not defined'') does if
+not. The <em/command/ may be any valid fraction of a configuration file.
 
-Example:
+All names of variables and functions may be tested. Additionally, the
+following compile-features may be tested when prefixed with 'feature_':
+ncurses, slang, iconv, idn, dotlock, standalone, pop, nntp, imap, ssl,
+gnutls, sasl, sasl2, libesmtp, compressed, color, classic_pgp,
+classic_smime, gpgme, header_cache.
+
+Examples follow.
+
+To only source a file with IMAP related settings only if IMAP support is
+compiled in, use:
 <tscreen><verb>
-ifdef imap_keepalive 'source ~/.mutt/imap_setup'
+ifdef feature_imap 'source ~/.mutt-ng/imap_setup'
+# or
+# ifdef imap_user 'source ~/.mutt-ng/imap_setup'
+# or
+# ...
 </verb></tscreen>
 
+To exit mutt-ng directly if no NNTP support is compiled in:
+<tscreen><verb>
+ifndef feature_nntp 'push q'
+# or
+# ifndef newsrc 'push q'
+# or
+# ...
+</verb/</tscreen>
