setpath path_list

Set the path used to find source, object, etc. files. path_list is a colon-separated list of directories. If any directory has a colon character in it, escape it with a backslash. The special directory name, $expts, refers to the set of current experiments, in the order in which they were loaded; you can abbreviate it with a single $ character.

The default setting is: $expts:.. The compiled-in full pathname is used if a file is not found in searching the current path setting.

setpath with no argument prints the current path.
