+=head1 DESCRIPTION
+
+This command is used to generate list of algorithms or disabled
+features.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-help>
+
+Display a usage message.
+
+=item B<-verbose>
+
+Displays extra information.
+The options below where verbosity applies say a bit more about what that means.
+
+=item B<-1>
+
+List the commands, digest-commands, or cipher-commands in a single column.
+If used, this option must be given first.
+
+=item B<-commands>
+
+Display a list of standard commands.
+
+=item B<-digest-commands>
+
+Display a list of message digest commands, which are typically used
+as input to the L<openssl-dgst(1)> or L<openssl-speed(1)> commands.
+
+=item B<-cipher-commands>
+
+Display a list of cipher commands, which are typically used as input
+to the L<openssl-dgst(1)> or L<openssl-speed(1)> commands.
+
+=item B<-digest-algorithms>, B<-kdf-algorithms>, B<-mac-algorithms>,
+B<-cipher-algorithms>
+
+Display a list of cipher, digest, kdf and mac algorithms.
+See L</Display of algorithm names> for a description of how names are
+displayed.
+
+In verbose mode, the algorithms provided by a provider will get additional
+information on what parameters each implementation supports.
+
+=item B<-public-key-algorithms>
+
+Display a list of public key algorithms, with each algorithm as
+a block of multiple lines, all but the first are indented.
+
+=item B<-public-key-methods>
+
+Display a list of public key method OIDs.
+
+=item B<-engines>
+
+Display a list of loaded engines.
+
+=item B<-disabled>
+
+Display a list of disabled features, those that were compiled out
+of the installation.
+
+=item B<-objects>
+
+Display a list of built in objects, i.e. OIDs with names.  They're listed in the
+format described in L<config(5)/ASN1 Object Configuration Module>.
+
+=item B<-options> I<command>
+
+Output a two-column list of the options accepted by the specified I<command>.
+The first is the option name, and the second is a one-character indication
+of what type of parameter it takes, if any.
+This is an internal option, used for checking that the documentation
+is complete.

+
+=head2 Display of algorithm names
+
+Algorithm names may be displayed in one of two manners:
+
+=over 4
+
+=item Legacy implementations
+
+Legacy implementations will simply display the main name of the
+algorithm on a line of its own, or in the form C<<foo > bar>> to show
+that C<foo> is an alias for the main name, C<bar>
+
+=item Provided implementations
+
+Implementations from a provider are displayed like this if the
+implementation is labeled with a single name:
+
+ foo @ bar
+
+or like this if it's labeled with multiple names:
+
+ { foo1, foo2 } @bar
+
+In both cases, C<bar> is the name of the provider.
