40 * Notes for improving compacting:
41 * if you add a jsdoc comment
48 * directly before an eval statement, it will compress all the code around the eval,
49 * and not rename the variables 'avarname'
51 * Dont try running this on a merged uncompressed large file - it's used to be horrifically slow. not sure about now..
52 * Best to use lot's of small classes, and use it to merge, as it will cache the compaction
56 * Notes for translation
57 * - translation relies on you using double quotes for strings if they need translating
58 * - single quoted strings are ignored.
60 * Generation of indexFiles
61 * - translateIndex = the indexfile
