- *   TraceKit.report(exception)

- *
- * Supports:

- *   - Opera:   full stack trace with line and column numbers
- *   - Chrome:  full stack trace with line and column numbers
- *   - Safari:  line and column number for the top frame only; some frames
- *              may be missing, and column number is not guaranteed
- *   - IE:      line and column number for the top frame only; some frames
- *              may be missing, and column number is not guaranteed
- *
- * In theory, TraceKit should work on all of the following versions:
- *   - IE5.5+ (only 8.0 tested)
- *   - Firefox 0.9+ (only 3.5+ tested)
- *   - Opera 7+ (only 10.50 tested; versions 9 and earlier may require

- *   - Safari 3+ (only 4+ tested)
- *   - Chrome 1+ (only 5+ tested)
- *   - Konqueror 3.5+ (untested)
- *
- * Requires TraceKit.computeStackTrace.
- *
- * Tries to catch all unhandled exceptions and report them to the
- * subscribed handlers. Please note that TraceKit.report will rethrow the
- * exception. This is REQUIRED in order to get a useful stack trace in IE.
- * If the exception does not reach the top of the browser, you will only
- * get a stack trace from the point where TraceKit.report was called.
- *
- * Handlers receive a stackInfo object as described in the

-/**
- * TraceKit.computeStackTrace: cross-browser stack traces in JavaScript
- *
- * Syntax:
- *   s = TraceKit.computeStackTrace(exception) // consider using TraceKit.report instead (see below)
- * Returns:
- *   s.name              - exception name
- *   s.message           - exception message
- *   s.stack[i].url      - JavaScript or HTML file URL
- *   s.stack[i].func     - function name, or empty for anonymous functions (if guessing did not work)
- *   s.stack[i].args     - arguments passed to the function, if known
- *   s.stack[i].line     - line number, if known
- *   s.stack[i].column   - column number, if known
- *   s.stack[i].context  - an array of source code lines; the middle element corresponds to the correct line#
- *
- * Supports:
- *   - Firefox:  full stack trace with line numbers and unreliable column
- *               number on top frame
- *   - Opera 10: full stack trace with line and column numbers
- *   - Opera 9-: full stack trace with line numbers
- *   - Chrome:   full stack trace with line and column numbers
- *   - Safari:   line and column number for the topmost stacktrace element
- *               only
- *   - IE:       no line numbers whatsoever
- *
- * Tries to guess names of anonymous functions by looking for assignments
- * in the source code. In IE and Safari, we have to guess source file names
- * by searching for function bodies inside all page scripts. This will not
- * work for scripts that are loaded cross-domain.
- * Here be dragons: some function names may be guessed incorrectly, and
- * duplicate functions may be mismatched.
- *
- * TraceKit.computeStackTrace should only be used for tracing purposes.
- * Logging of unhandled exceptions should be done with TraceKit.report,
- * which builds on top of TraceKit.computeStackTrace and provides better
- * IE support by utilizing the window.onerror event to retrieve information
- * about the top of the stack.
- *
- * Note: In IE and Safari, no stack trace is recorded on the Error object,
- * so computeStackTrace instead walks its *own* chain of callers.
- * This means that:
- *  * in Safari, some methods may be missing from the stack trace;
- *  * in IE, the topmost function in the stack trace will always be the
- *    caller of computeStackTrace.
- *
- * This is okay for tracing (because you are likely to be calling
- * computeStackTrace from the function you want to be the topmost element
- * of the stack trace anyway), but not okay for logging unhandled
- * exceptions (because your catch block will likely be far away from the
- * inner function that actually caused the exception).
