+=head1 NAME
+
+pkeyparam - public key algorithm parameter processing tool
+
+=head1 SYNOPSIS
+
+B<openssl> B<pkeyparam>
+[B<-in filename>]
+[B<-out filename>]
+[B<-text>]
+[B<-noout>]
+[B<-engine id>]
+
+=head1 DESCRIPTION
+
+The B<pkey> command processes public or private keys. They can be converted
+between various forms and their components printed out.
+
+=head1 COMMAND OPTIONS
+
+=over 4
+
+=item B<-in filename>
+
+This specifies the input filename to read parameters from or standard input if
+this option is not specified.
+
+=item B<-out filename>
+
+This specifies the output filename to write parameters to or standard output if
+this option is not specified.
+
+=item B<-text>
+
+prints out the parameters in plain text in addition to the encoded version. 
+
+=item B<-noout>
+
+do not output the encoded version of the parameters.
+
+=item B<-engine id>
+
+specifying an engine (by it's unique B<id> string) will cause B<req>
+to attempt to obtain a functional reference to the specified engine,
+thus initialising it if needed. The engine will then be set as the default
+for all available algorithms.
+
+=back
+
+=head1 EXAMPLE
+
+Print out text version of parameters:
+
+ openssl pkeyparam -in param.pem -text
+
+=head1 NOTES
+
+There are no B<-inform> or B<-outform> options for this command because only
+PEM format is supported because the key type is determined by the PEM headers.
