Bash scripting, looping through a environmental variable path list?
===

I want to perform a loop from a path list that I have gotten from a echo $VARIABLE command.

For example:

Echo $MANPATH will return

/usr/lib:/usr/sfw/lib:/usr/info

so that is three different paths, each separated by a colon. I want to loop though each of those paths. Is there a way to do that? Thanks.
