jas-blockly
Blockly Library
Extremely hard to install!
First download Blockly. Then download google closure library.
https://developers.google.com/closure/library/
Expand the Blockly Library into a sub directory. Then expand the Closure Library. Rename the directory from google-closure-library to closure-library.
Thus
/MYDOWNLOAD/blockly /MYDOWNLOAD/closure-library
Then run python build.py. This builds the library.
Copy the update into jas-blockly dir. We need:
blockly_compressed.js blocks_compressed.js javascript_compress.js messages.js
blockly_support.js - Keep this!
