I've developed a file (let's call it mypdf.rb) which extends the module
PDF::Writer with some additional methods. This enables me to produce PDF
documents of a very specific nature for a project I am working on.
I've developed and tested this outside the RoR framework. Now I want to use
it within the context of a RoR application.
Where should I put the mypdf.rb file, so that I can define objects from the
class ? Somewhere within the RoR application framework code ? Or
somewhere in the Ruby install tree ?
