3 | # |
---|
4 | # This object represents an entire tool defined by Rappture. |
---|
5 | # Each tool resides in an installation directory with other tool |
---|
6 | # resources (libraries, examples, etc.). Each tool is defined by |
---|
7 | # its inputs and outputs, which are tied to various widgets in the |
---|
8 | # GUI. Each tool tracks the inputs, knows when they're changed, |
---|
9 | # and knows how to run itself to produce new results. |
