Easy way to track versions and even display the svn revision number

version_info.rb

module VersionInfo
	#Version number file
	MAJOR_VERSION = 1
	ENHANCE_VERSION = 3
	FIX_VERSION	= 2
	BETA_FLAG = true
	RC_FLAG = false

	def self.get_svn_revision
		`svn info`.split("\n")[4][/\d+/].to_i
	end

	def is_beta?
		BETA_FLAG
	end
	
	def self.get_version_number
		BETA_FLAG == true ? 	beta = " beta " : ""
		RC_FLAG == true ? rc = " release candidate " : ""
		version = "(r.#{get_svn_revision})" unless RAILS_ENV == "production"
		"#{MAJOR_VERSION}.#{ENHANCE_VERSION}.#{FIX_VERSION}#{rc}#{beta}#{version}"
	end
end
