137 =head1 HISTORY
138
139 =for openssl foreign manual apropos(1)
140
141 Initially, the manual page entry for the C<openssl I<cmd>> command used
142 to be available at I<cmd>(1). Later, the alias B<openssl-I<cmd>>(1) was
143 introduced, which made it easier to group the openssl commands using
144 the L<apropos(1)> command or the shell's tab completion.
145
146 In order to reduce cluttering of the global manual page namespace,
147 the manual page entries without the 'openssl-' prefix have been
148 deprecated in OpenSSL 3.0 and will be removed in OpenSSL 4.0.
