$! CA - wrapper around ca to make it easier to use ... basically ca requires
$!      some setup stuff to be done before you can use it and this makes
$!      things easier between now and when Eric is convinced to fix it :-)
$!
$! CA -newca ... will setup the right stuff
$! CA -newreq ... will generate a certificate request 
$! CA -sign ... will sign the generated request and output 
$!
$! At the end of that grab newreq.pem and newcert.pem (one has the key 
$! and the other the certificate) and cat them together and that is what
$! you want/need ... I'll make even this a little cleaner later.
$!

$! 12-Jan-96 tjh    Added more things ... including CA -signcert which
$!                  converts a certificate to a request and then signs it.
$! 10-Jan-96 eay    Fixed a few more bugs and added the SSLEAY_CONFIG
$!                 environment variable so this can be driven from
$!                 a script.
$! 25-Jul-96 eay    Cleaned up filenames some more.
$! 11-Jun-96 eay    Fixed a few filename missmatches.
$! 03-May-96 eay    Modified to use 'openssl cmd' instead of 'cmd'.
$! 18-Apr-96 tjh    Original hacking
