What is the <appname>.rb file in /lib typically used for in a Ruby project?
ruby, structure
Solution
Usually (and certainly in the example of rake) the `appname.rb` file is a shortcut to require a lot of other files. If you take a look at that file in the Rake project on GitHub, most of what it does is require files in the `lib/rake` directory and include modules as necessary. That file is what lets you `require 'rake'` without having to know what individual files rake needs.
Problem
In reference to this question: Ideal ruby project structure I noticed that appname.rb is in lib, and is top level. I was reading through a little of the Rake source code on Github, and I noticed their project structure is pretty much the same. They have a top level 'rake.rb' file in /lib, but I'm not sure what it's there for. In The Pickaxe (Programming Ruby 1.9), they show an example of structuring a small project, with pretty much the same directory structure above, but there is no mention of the usage of a top level .rb in /lib. So, my question is: What exactly is this thing typically used for in a Ruby project? Sorry if this is a stupid question, I'm sure it is, but I'm relatively new to Ruby. I don't know that much Ruby-foo right now. ;) Thanks.
