I downloaded Ext 3.1, and ran jsbuilder2 on the source using the jsb2 file included in the 3.1 download package:

Code:
java.exe -jar jsbuilder2.jar --projectFile "c:\development\js builder\staging\ext.jsb2" --homeDir "c:\development\js builder\compiled"
I then compared the resulting ext-all-debug.js to the ext-all-debug.js in the 3.1 download package. I expected that they would be identical, but they are not. There are commetns speckled throughout the .js created using jsbuilder. I thought Ext uses jsbuilder themselves to create the "-all" files. Is there a way to force comments to be removed?
