"Classpath" is stored in $: and $LOAD_PATH (they point to the same
object).  Shell variable is $RUBYLIB.

Typically files are named similar to their content, e.g.

file mypro.rb

module MyPro
end

# optional:
require 'mypro/c1'

file mypro/c1.rb

require 'mypro'

module MyPro
  class C1
  end
end

etc.

Use via require 'mypro/c1' or require 'mypro'.

Alternative:

file mypro.rb

module MyPro
  autoload 'C1', 'c1'
end

file mypro/c1.rb

require 'mypro'

module MyPro
  class C1
  end
end

Use via require 'mypro/c1' or require 'mypro'.

You can see this in various standard libraries as well.  You can look
at REXML for example.

Kind regards

robert
