 Parametar C<filter> defines user supplied snippets of perl code which can
 be use with C<filter{...}> notation.
 
+C<prefix> is used to form filename for database record (to support multiple
+source files which are joined in one database).

 Recommended parametar C<lookup_regex> is used to enable parsing of lookups
 in structures. If you pass this parametar, you must also pass C<lookup>
 which is C<WebPAC::Lookup> object.
