HISTORY
Initially, the manual page entry for the "openssl cmd" command used to
be available at cmd(1). Later, the alias openssl-cmd(1) was introduced,
which made it easier to group the openssl commands using the apropos(1)
command or the shell's tab completion.
In order to reduce cluttering of the global manual page namespace, the
manual page entries without the 'openssl-' prefix have been deprecated
in OpenSSL 3.0 and will be removed in OpenSSL 4.0.
