+// Determines whether a certain driver bug exists in the current system.
+// A valid gpu_driver_bug_list.json file are in the format of
+// {
+//   "version": "x.y",
+//   "entries": [
+//     { // entry 1
+//     },
+//     ...
+//     { // entry n
+//     }
+//   ]
+// }
+//
+// Each entry contains the following fields (fields are optional unless
+// specifically described as mandatory below):
+// 1. "id" is an integer.  0 is reserved.  This field is mandatory.
+// 2. "os" contains "type" and an optional "version". "type" could be "macosx",
+//    "linux", "win", "chromeos", or "any".  "any" is the same as not specifying
+//    "os".
+//    "version" is a VERSION structure (defined below).
+// 3. "vendor_id" is a string.  0 is reserved.
+// 4. "device_id" is an array of strings.  0 is reserved.
+// 5. "multi_gpu_style" is a string, valid values include "optimus", and
+//    "amd_switchable".
+// 6. "multi_gpu_category" is a string, valid values include "any", "primary",
+//    and "secondary".  If unspecified, the default value is "primary".
+// 7. "driver_vendor" is a STRING structure (defined below).
+// 8. "driver_version" is a VERSION structure (defined below).
+// 9. "driver_date" is a VERSION structure (defined below).
+//    The version is interpreted as "year.month.day".
+// 10. "gl_vendor" is a STRING structure (defined below).
+// 11. "gl_renderer" is a STRING structure (defined below).
+// 12. "perf_graphics" is a FLOAT structure (defined below).
+// 13. "perf_gaming" is a FLOAT structure (defined below).
+// 14. "perf_overall" is a FLOAT structure (defined below).
+// 15. "machine_model" contais "name" and an optional "version".  "name" is a 
+//     STRING structure and "version" is a VERSION structure (defined below).
+// 16. "gpu_count" is a INT structure (defined below).
+// 17  "cpu_info" is a STRING structure (defined below).
+// 18. "exceptions" is a list of entries.
+// 19. "features" is a list of gpu switching options.
+//     This field is mandatory.
+// 20. "description" has the description of the entry.
+// 21. "webkit_bugs" is an array of associated webkit bug numbers.
+// 22. "cr_bugs" is an array of associated webkit bug numbers.
+// 23. "browser_version" is a VERSION structure (defined below).  If this
+//     condition is not satisfied, the entry will be ignored.  If it is not
+//     present, then the entry applies to all versions of the browser.
+// 24. "disabled" is a boolean. If it is present, the entry will be skipped.
+//     This can not be used in exceptions.
+//
+// VERSION includes "op", "style", "number", and "number2".  "op" can be any of
+// the following values: "=", "<", "<=", ">", ">=", "any", "between".  "style"
+// is optional and can be "lexical" or "numerical"; if it's not specified, it
+// defaults to "numerical".  "number2" is only used if "op" is "between".
+// "between" is "number <= * <= number2".
+// "number" is used for all "op" values except "any". "number" and "number2"
+// are in the format of x, x.x, x.x.x, etc.
+// Only "driver_version" supports lexical style if the format is major.minor;
+// in that case, major is still numerical, but minor is lexical. 
+//
+// STRING includes "op" and "value".  "op" can be any of the following values:
+// "contains", "beginwith", "endwith", "=".  "value" is a string.
+//
+// FLOAT includes "op" "value", and "value2".  "op" can be any of the
+// following values: "=", "<", "<=", ">", ">=", "any", "between".  "value2" is
+// only used if "op" is "between".  "value" is used for all "op" values except
+// "any". "value" and "value2" are valid float numbers.
+// INT is very much like FLOAT, except that the values need to be integers.
