 # 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[-nodes] ... 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 'ssleay cmd' instead of 'cmd'.
 # 18-Apr-96 tjh    Original hacking
 #
 # Tim Hudson

 # 27-Apr-98 snh    Translation into perl, fix existing CA bug.
