I have a webpage that creates images, html and midi files
automatically using ruby scripts. The problem is, that
everything is a ruby script, but I want to tell httrack in
advance that 
- normally a ruby script is text/html, 
- except for fingering.rb which is image/png 
- and hearchord.rb which is audio/midi

How would I do that?
Right know httrack is accessing millions of times these
scripts to find out which mime type they have.

best regards,

brian
