Putting these in rb_main.rb is typically a good idea. -- This might be obvious, but just in case: the "File.join(File.dirname..." patern will only work in rb_main.rb or any other file in the same directory. If you've put your class definition files in lib/ then you'll need to change the relative path. > 1.

So, what I do is to just collect all the contents of the "lib" directories for all the gems and put them together (either directly in my own lib/ or in vendor/lib/). There's no reason for the extra directories...just adds complexity. > 2. All I want to do is sign records for later comparison.
