-== tempdir.rb - provides class Tempdir
-
-=== Synopsis
-In order to
-
-1. create a temporary directory with a name starting with "hoge", 
-2. show the name of that directory, and
-3. show its properties with the system "ls -dl" command:
-
-  require 'tempdir'
-
-  d = Tempdir.new("hoge")
-  p d.to_s
-  system("ls", "-dl", d.to_s)
-
-After the run, the directory will appear to be removed. That is: if you
-are not running inside it, which may provide you a means to create a
-directory with a unique name that will be available after the run.
-
-=== Description
-<i>tempdir.rb</i> provides the Tempdir class, which is analogous to the
-Tempfile class, but manipulates temporary directories. Derived from a
-proposal of [e-mail]. He added the class to
-tempfile.rb, but since it does not seem to appear in cvs, I'll keep
-it apart in tempdir.rb.
