@@ -3,3 +3,10 @@ Hey, trying to get ikiwiki working on my account on a shared webserver. Actually
 My first thought was that this is a Perl CGI and I would need to change the shebang to point to the unusual location of Perl on this server, it's at /usr/pkg/bin/perl. But when I looked at ikiwiki.cgi I found it was a binary file.
 
 Why is it a binary? And what can I do about this error?
