RAA - rubyscript2exe/0.1.15

RubyScript2Exe transforms your Ruby script into a standalone
Windows executable. You can look at it as a "compiler". Not in
the sense of a source-code-to-byte-code compiler, but as a
"collector", for it collects all necessary files to run your
script on an other machine. Anyway, the result is the same: a
standalone exe-file. And that's what we want!

The combination of Tar2RubyScript and RubyScript2Exe is of
special interest: A complete Ruby application can be
distributed as one executable (for Windows). Tar2RubyScript
creates a standalone Ruby script (or RBA, Ruby Archive) of the
application and its directory. This RBA can run on "the Ruby
platform". This means that Ruby itself must be installed on the
targeted system. RubyScript2Exe avoids this dependency by
combining the RBA and Ruby itself into one executable.

Because of the gathering of files from your Ruby installation,
RubyScript2Exe can only run on Windows.

There is one more advantage: Because there are some
incompatibilities between Ruby 1.6 and 1.8, you have to test
your script with both versions. Unless you distribute your
version with your script...
