//// Convert JavaScript code to one line bookmarklet
// http://en.wikipedia.org/wiki/Bookmarklet
// http://ru.wikipedia.org/wiki/Букмарклет

// Arguments:
//   -saveSpaces=0         - replace multiple spaces with one
//              =1         - don't replace spaces inside lines
//              =2         - only replace new lines
//   -removeNewLines=true  - remove new lines instead of replace them with space
//   -saveComments=0       - sum of flags: 1 - save block comments, 2 - save line comments

// Usage:
//   Call("Scripts::Main", 1, "converter.js")
//   Call("Scripts::Main", 1, "converter.js", "-saveSpaces=0 -removeNewLines=true -saveComments=3")
