Reads a file with the output from gem list and installs the gems

rawclone.rb

#! /usr/bin/ruby

# So you want to start developing an already "woking" project. No
# bundle, config.gem's not present or messing up dependencies. Fear
# not!
# Do a "gem list" wherever the project is already working
# (production?, some colleage machine?). Make a file with this format: 
#
# chronic (0.2.3)
# colored (1.1)
# daemons (1.0.10)
# fastercsv (1.4.0)
# fastthread (1.0.7)
# feed-normalizer (1.5.1)
# feedtools (0.2.26)
# ferret (0.11.4)
# gcnovus-avatar (0.0.7)
# gem_plugin (0.2.3)
# gettext (1.93.0, 1.9.0)
#
# Run "rawclone yourgemsfile" on your machine and your ready to go.
#
# Tip 1: You could add this file to your repo for easy sharing and
# faster developing machine setup
#
# Tip 2: I would not recomend this without a proper rvm installation.
#
# Tip 3: Seriously install, configure and learn to use rvm.
#
# Tip 4: Eat more vegetables and be happy.
