* user's home directory.

* File.expand_path("~oracle/bin") #=> "/home/oracle/bin"
* File.expand_path("../../bin", "/tmp/x") #=> "/bin"
*
* A simple example of using <i>dir_string</i> is as follows.
* File.expand_path("ruby", "/usr/bin") #=> "/usr/bin/ruby"
*
* A more complex example which also resolves parent directory is as follows.
* Suppose we are in bin/mygem and want the absolute path of lib/mygem.rb.
*
* File.expand_path("../../lib/mygem.rb", __FILE__)
* #=> ".../path/to/project/lib/mygem.rb"
*
* So first it resolves the parent of __FILE__, that is bin/, then go to the
* parent, the root of the project and appends +lib/mygem.rb+.
