-# 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 'ssleay cmd' instead of 'cmd'.
-# 18-Apr-96 tjh Original hacking
