2001-12-06  Jon Trowbridge  <trow@ximian.com>

	* e-msg-composer.c (executed_file_output): Added.  Executes the
	given file and returns its output as a string.
	(get_file_content): Stats the file to see if it is executable.
	If it is, execute it and return the string.  If not, just read
	the file and return the contents.
