/*
  test1.c

  Create a message, save it.

  Retrieve message, compare content.


  Operations:
	writing/loading from different types of streams
	reading/writing different content
	reading/writing different encodings
	reading/writing different charsets

  Just testing streams:
  	different stream types
	different file ops
	seek, eof, etc.
