Reclaiming disk space from tablespaces

Hi!

	We have Oracle 6.0 running on a TI SVR4 platform. We had to add 
	tablespace of about 20 Meg temporarily to one of our tablespaces 
	for a research project.
	Accidentally we ended up adding up about the same
	amount of space to our System tablespace too. Now that we are
	running low on disk space on our machine we want to reclaim the
	disk space from these tablespaces without losing any data or 
	corrupting the database. Would someone please help me on this
	task?
