Subject: [ANN] nfc 2.0.0 Released

nfc version 2.0.0 has been released!

* <http://seattlerb.rubyforge.org>

NFC is a ruby wrapper for the Near Field Communication library.  The Near
Field Communication library works with many USB RFID readers, so this gem
lets you read RFID tags.

Changes:

### 2.0.0 / 2009-08-07

* 2 major enhancements

  * Switched from FFI to a C backend
  * Now depends on libnfc 1.2.x

## FEATURES/PROBLEMS:

* Only supports ISO1443A (MIFARE) tags right now.

## SYNOPSIS:

  require 'nfc'

  # Read your tag and print the info.
  p NFC.instance.find

  # NFC#find will return immidiately, which means you should have a tag
  # sitting on the reader when running it.  If you'd like it to block until
  # it detects a tag, give find a block like so:

  NFC.instance.find do |tag|
    p tag
  end

  # You can even run in an infinite loop if you'd like to continually find
  # tags:

  loop do
    NFC.instance.find do |tag|
      p tag
    end
  end

## REQUIREMENTS:

* A USB RFID reader.  I'm using the touchatag[http://touchatag.com].
* libnfc

## INSTALL:

First install libnfc[http://libnfc.org/]
I installed libnfc like this:

  $ ./configure --prefix=/usr/local
  $ make && make install

The install the gem:

  $ sudo gem install nfc

NOTE!!!!  The nfc gem requires libnfc version 1.2.0 or greater!
