Short ad: MCL code for graphing trees (DAG) such as:

- class hierarchies (via a few buttons in an inspector window)
- window hierarchies
- lists
- file system
...
- easily write your own

Based on over a decade old GETA code. See it to believe it - contains 
only minor bit-decay.

Installation instructions:
--------------------------

1. Download the stuffed folder from 
http://sabine.hut.fi/www/Lisp/inspector-hacks.sit

2. Unstuff and place the folder in your MCL folder, top-level 
placement is expected.
    There is a read-me.text file inside the folder. Read it for the 
the long ad (i.e., documentation) to see how to use it.

3. Load or eval the contents of the file named %load-inspector-hacks.lisp
    A few demo calls are at the end of this file to test out the 4 
different graphers.

4. Don't pass up on the chance of adding colour to your inspector 
window: if you are inspecting a fixnum in the RGB color range, a 
rectangle will appear after the RGB values in the coded colour. See 
http://sabine.hut.fi/www/Lisp/Color-inspector-mod.lisp Has been 
useful when dealing with colours. This was more of an exercise in 
getting non-textual output to display in the inspector.
