 ============
 
 A browser firendly VCS file generator written entirely in javascript!!!!!!
+
+
+The source has forked and compiled versions of the following projects:
+* FileSaver.js (https://github.com/eligrey/FileSaver.js)
+* Blob.js (https://github.com/eligrey/Blob.js)
+
+I've compressed them and included them into the source.
