Strategy for handling non-ASCII with Mail

	# Escape non-ASCII characters and forward slashes as unicode escape sequences,
	# but with forward slashes instead of backslashes, since backslashes already have meaning
	def asciiify(str)
	str.unpack('U*').map { \|i\|
	(i == 47 \|\| i == 92 \|\| i > 127) ? "/u" + i.to_s(16).rjust(4, '0') : i.chr
	}.join
	end

	# Decode "forward slashed" unicode escape sequences
	def deasciiify(str)

Quick and dirty utility to list all the objects in an S3 bucket with a certain prefix and, for any whose key matches a pattern, read the file line by line and print any lines that match a second pattern. Adjust constants as appropriate. Usage: sbt 'run <AWS access key ID> <AWS secret key>'

	* Directory structure should be:
	* - project_root
	* - build.sbt (see below)
	* - src
	* - main
	* - scala
	* - S3Inspect.scala
