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