Working a bit on LeJOS
 Lego Java Robot stuff; Julie is playing around with them.

 * Installed java, javac, as well as netbeans 
   (/usr/local/bin for binaries;
    /usr/local/jdk1.5.0_06 and netbeans-4.1 for sources)

 * downloaded 

   LeJOS 2.1 and docs
    http://easynews.dl.sourceforge.net/sourceforge/lejos/lejos_2_1_0.tar.gz
    http://voxel.dl.sourceforge.net/sourceforge/lejos/lejos_2_1_0.doc.tar.gz
   
   Intelligo (RX simulator, undergrad 2002 project)
    http://homepages.inf.ed.ac.uk/s0237680/intellego/intellego.html

  
 * trying to configure & compile the rest of it :

   1. lejos

     $ cd lejos_2_1_0
     $ make
     ... 
     javac -target 1.1 -classpath classes `find classes -name '*.java'`
     javac: target release 1.1 conflicts with default source release 1.5
     make: *** [core_classes] Error 2
     # So, leaving out the target :n
     $ javac -classpath classes `find classes -name '*.java'`
     $ cd ..

   2. intelligo
     index.html : edit Intelligo.sh and util/setup.sh appropriately.
     So I copied both to *.orig, and changed start both to
       export BASE=/var/www/cs/.../programming_workshop/lejos
       export INTELLEGO_HOME=$BASE/Intellego
       export LEJOS_HOME=$BASE/lejos_2_1_0
     $ make
     $ make javadoc
     $ make html

   It was complaining of some permission issues, so as root :
     $ chmod -R go+rwx .

  * Hey hey ... it works !
     $ ./Intelligo.sh
     ... and use the menus to pick "light world" and "light seeking robot"
