I cant get it to run `javac -cp '.:processing.core.jar:pack.core.jar' TestMultiSheets1b.java` ``` TestMultiSheets1b.java:9: error: package processing.core does not exist import processing.core.PApplet; ``` ``` [ @ Dalsoo-Bin-Packing]$ ls * dalsoo.jar LICENSE multiple.png...

thank you! The core.jar I found seems to be different.
