rprogram version 0.1.5 has been released!

RProgram is a library for creating wrappers around command-line programs.
RProgram provides a Rubyful interface to programs and all their options
or non-options. RProgram can also search for programs installed on a
system.

Changes:

### 0.1.5 / 2009-01-14

* Use Kernel.system in RProgram::Program#run, instead of Open3.popen3:
* popen3 is not well supported on Windows.
* win32-open3 does not allow for the execution of single programs with
separate command-line arguments. Instead, it merely executes a command
string in command.com. This seems to allow arbitrary command injection
via command-line arguments.
* RProgram::Program#run will now return either +true+ or +false+,
depending on the exit status of the program.
* Added some missing documentation.
