Improve error handling. Make --list actually return something useful,

2003-01-13  Glynn Foster  <glynn.foster@sun.com>

	* src/main.c: Improve error handling.
	* src/tree.c: Make --list actually return something
	useful, although I still need to actually seperate
	things out so it's actually decipherable.

	* TODO: Update accordingly.
