module Shepherd
	
	# A class through which you can connect to the database.
	# 
	# == Usage
	# 
	#     module Shepherd
	#        Db.new.execute "sql query"
	#     end
	# 
	# Inside a +Shepherd::Command::Klass+, it would look like:
	# 
	#     module Shepherd::Command
	#        class Klass
	#           def init
	#              Shepherd::Db.new.execute "sql query"
	#           end
	#        end
	#     end
	# 
	# Here is {SQLite3 documantation}[http://sqlite-ruby.rubyforge.org/sqlite3/faq.html]. +Shepherd::Db.new+ is equal to +SQLite3::Database.new+ so there you've got a complete documentation.
	# 
	class Db
