Here is the PCSC sample in Ruby language I promised in PC/SC sample in different languages.
A PC/SC Wrapper for Ruby also exists at Smart-card communication, straight from ruby.. The latest version is 0.4.11 from 2009. I used an older version 0.3.1 when I worked with this wrapper.
You first need to install ruby and the other components needed for the compilation of smartcard for Ruby.
Then fetch the archive smartcard-0.4.11.gem
Nothing more to add. If you are a Ruby user you may be interested by this wrapper.

Conclusion
Nothing more to add. If you are a Ruby user you may be interested by this wrapper.
This is dummy text. It is not meant to be read. Accordingly, it is difficult to figure out when to end it. But then, this is dummy text. It is not meant to be read. Period.
