+KERBEROS4 FTP TRANSFER
+
+  Curl supports kerberos4 for FTP transfers. You need the kerberos package
+  installed and used at curl build time for it to be used.
+
+  First, get the krb-ticket the normal way, like with the kauth tool. Then use
+  curl in way similar to:
+
+        curl --krb4 private ftp://krb4site.com -u username:fakepwd
+
+  There's no use for a password on the -u switch, but a blank one will make
+  curl ask for one and you already entered the real password to kauth.
