    3: # CA - wrapper around ca to make it easier to use ... basically ca requires
    4: #      some setup stuff to be done before you can use it and this makes
    5: #      things easier between now and when Eric is convinced to fix it :-)
    6: #
    7: # CA -newca ... will setup the right stuff
    8: # CA -newreq ... will generate a certificate request 
    9: # CA -sign ... will sign the generated request and output 
   10: #
   11: # At the end of that grab newreq.pem and newcert.pem (one has the key 
   12: # and the other the certificate) and cat them together and that is what
   13: # you want/need ... I'll make even this a little cleaner later.

   16: # 12-Jan-96 tjh    Added more things ... including CA -signcert which
   17: #                  converts a certificate to a request and then signs it.
   18: # 10-Jan-96 eay    Fixed a few more bugs and added the SSLEAY_CONFIG
   19: #                  environment variable so this can be driven from
   20: #                  a script.
   21: # 25-Jul-96 eay    Cleaned up filenames some more.
   22: # 11-Jun-96 eay    Fixed a few filename missmatches.
   23: # 03-May-96 eay    Modified to use 'ssleay cmd' instead of 'cmd'.
   24: # 18-Apr-96 tjh    Original hacking
