Updates to Project #2 Skeleton and Description

Last Modified: 10/28/2002


1. 10/20/2002: Corrected test1.out.  Copy the new one from 
   ~cs61b/hw/proj2/test1.out.  

2. 10/20/2002: Clarfication: If you discover that two particles have 
     identical positions, you may ignore the second of them.  We'll try 
     not to test this case, but don't let it cause an infinite loop in
     your program (trying to subdivide your tree so that the two points
     are separated).

3. 10/20/2002: To test your project with our classes, use the commands
   'p2java' in place of java, or 'p2gjdb' in place of gjdb, as
   follows:

   * p2java --util track
     p2gjdb --util track

       Run your track class with our util package.

   * p2java --track track
     p2gjdb --track track

       Run our track class with your util package.

   WARNING: Assume there are errors in our classes!  They do NOT
   define the project; the Project #2 handout does (with on-line
   updates).  Please report all errors you find to us (with bug-
   submit).

4. Correct 'check' target in Makefile, so that test sets that are not
   supposed to produce a DATA file will work.
