+Troubleshooting
+---------------
+
+If you have trouble using Freeze for a large program, it's probably
+best to start playing with a really simple program first (like the
+file hello.py).  If you can't get that to work there's something
+fundamentally wrong -- read the text above to find out how to install
+relevant parts of Python properly and how to configure Freeze to find
+them.
+
+A common problem is having installed an old version -- rerunning "make
+libainstall" often clears up problems with missing modules or
+libraries at link time.
+
 
-Freeze is currently beta software.  You could email me a bug report.
-Please give as much context as possible -- "Freeze doesn't work" is
-not going to get much sympathy.  You could fix the bug and send me a
-patch.  You could learn Tcl.
+What is nfreeze.py?
+-------------------
 
-If you are thinking about debugging Freeze, start playing with a
-really simple program first (like "print 'hello world'").  If you
-can't get that to work there's something fundamentally wrong with your
-environment (or with your understanding of it).  Gradually build it up
-to use more modules and extensions until you find where it stops
-working.  After that, you're on your own -- happy hacking!
+The script nfreeze.py is an unsupported variant on freeze.py which
+creates all files in a temporary directory and runs "make" there.  It
+has the advantage that it doesn't overwrite files in the current
+directory, but the disadvantage is that it removes all files when it
+is finished.
