#!/bin/env ruby

# This is used to send email.
require 'net/smtp'


	# Helper method.
	# Append _appendage_ to end of string if it already doesn't exist
	# at the end of the string.
	class String #:nodoc:
		def appendIfMissing(appendage)
			return self if appendage.nil? || appendage.size < 1
			return appendage if size < 1
			if self[-appendage.size..-1] == appendage
				self
			else
				self + appendage
			end
		end
	end


	class String #:nodoc:
	  def blank?
		empty? || strip.empty?
	  end
	end


	# Print an error message.
	def err(msg, printRubyErr=false, fatal=true) #:nodoc:

		STDERR.print "\n#{$!}\n\n" if printRubyErr
		exit if fatal
		"### ERROR: #{msg}\n#{$!}\n"
	end



	# simple check of email address.

		addr
	end


	# Send email.
	def mail( od )
