Added write capabilities.
Small code fixes.
Update copyright notices.
Use single quotes in gem specification.
Make the gem executable into a wrapper.

Source code has been moved from bin/repman to lib/repman.rb, and bin/repman is now just a wrapper.
Initial working version for the native executable.
Convert line breaks from Windows to Unix format.
Add script for tests.
Use the new EasyOptions API in Ruby implementation.
Small source code reorganization.
Unify the command-line interfaces.

Both the Ruby and the native implementations now use the same command interface. The test script now runs the same tests for both versions.
Configure pacman automatically in native version.
Create configuration file earlier in Ruby version.

The Ruby implementation now creates repman.conf immediately when not found, just like the native version. Now both implementations create repman.conf and subsequently edit pacman.conf as needed.
