Release Name: 0.2

Notes:



Changes:
- Exceptions framework, including remote exceptions.  box['/does/not/exist'].contents with raise Rush::DoesNotExist, which is transmitted across the wire to the client.  All Rush exceptions can be found in exceptions.rb.  The interactive shell catches all rush-specific exceptions and surpresses the backtrace, for a one-line error message (comparable to bash).

- Box#bash: execute a bash shell command on the box.  Returns stdout; raises Rush::BashFailed with stderr as the exception message if the command did not return 0.

- Dir#bash, sames as Box#bash but runs the command from within the dir.

- FindBy extensions, which select members of an array on any arbitrary field.  find_by fetches the first match, find_all_by fetches all.  Examples: processes.find_by_pid(123), processes.find_by_cmdline(/mongrel_rails/)

- Process#parent and Process#children.  Get parent or child processes of a process, returned as a Rush::Process object (or an array of such, for children).

- Improved tab completion, contributed by Chihiro Ito.

- Windows process lookup, contributed by Gabriel Ware

- rushd writes a log to rushd.log, to better diagnose problems with a remote connection.

- Box#alive? to check if a box is responding to commands.

- Entry#exists? to check if a file or dir exists.

- Dir#purge to empty out the contents of a directory.  Equivalent to dir.contents.each { |f| f.destroy }

- Box#establish_connection takes a :timeout option, which can be a number of seconds, or :infinite, to be used for the ssh tunnel.  Default is still 9000 seconds (about 3 hours).

- Process#kill doesn't return until the process is really dead (code swiped from the god project's process.rb).  So processes.find_by_cmdline(/mongrel_rails/).each { |p| p.kill } will kill all your mongrels for sure, even wedged ones.

- The interactive shell now executes in the context of a Rush::Box.  This makes the internal implementation a bit cleaner, but also gives access to all the methods on Rush::Box.  For example, you can do: bash "adduser -m joe" rather than Rush::Box.new('localhost').bash "adduser -m joe"
