Yep.  I developed the .ej format back in 2001 because people were
telling me I had to use a single document format for all of MaraDNS'
documentation. I still use this format today, because it allows me to
have a single HTML-like file to make the nroff man pages, HTML
document files, as well as plain text files.

Thank you for patching the documentation as well as the code.  That
shows professionalism.
