Apache error "premature EOF in parsed file"

When Apache 1.3 says "premature EOF in parsed file".
What it means is "You've messed up the attribute syntax in a mod_include command".

Examples:

<!--#config timefmt=%s --> (no quotes)

<!--#set var='title' value='This title would've screwed things up' --> (apostrophe not escaped)
