Ralf S. Engelschall cb496082f8 Import the first cut for manual pages.
They are written in Perl's POD format for two reasons: First Perl is already
needed for SSLeay and second, POD is easy to write and maintain _AND_ created
nice looking NRoff manpages.

The idea is to have three manual pages:

  openssl(1) ... The manpage for the `openssl' program (formerly ssleay)
  crypto(3) .... The manpage for crypto.h/libcrypto.a
  ssl(3) ....... The manpage for ssl.h/libssl.a

The openssl(1) should be very similar to cvs(1), i.e.  it should document all
commands in a compact way.  And I've even created the first cut for an
overview of all 243 functions of the SSL API for ssl.pod. More to come...

=head1 NAME
SSL - OpenSSL SSL/TLS library
=head1 SYNOPSIS
=head1 DESCRIPTION
The OpenSSL B<ssl> library implements the Secure Sockets Layer (SSL v2/v3) and
Transport Layer Security (TLS v1) protocols. It provides a rich API which is
documented here.
=head1 HEADERS
Currently the OpenSSL B<ssl> library provides the following C header files
containing the prototypes for the data structures and and functions:
=over 4
=item B<ssl.h>
That's the common header file for the SSL/TLS API. Include it into your
program to make the API of the B<ssl> library available. It internally
includes both more private SSL headers and headers from the B<crypto> library.
=back
=head1 STRUCTURES
Currently the OpenSSL B<ssl> library functions deal with the following data
structures:
=over 4
=item B<SSL_CTX> (SSL Context)
=item B<SSL> (SSL Connection)
That's the SSL/TLS structure which is created by
a server or client per established connection.
=item B<SSL_METHOD> (SSL Method)
=item B<SSL_CIPHER> (SSL Cipher)
=item B<SSL_SESSION> (SSL Session)
=back
=head1 FUNCTIONS
Currently the OpenSSL B<ssl> library exports 143 API functions.
They are documented in the following:
