//	UKCrashReporterCheckForCrash:
//		This submits the crash report to a CGI form as a POST request by
//		passing it as the request variable "crashlog".
//	
//		KNOWN LIMITATION:	If the app crashes several times in a row, only the
//							last crash report will be sent because this doesn't
//							walk through the log files to try and determine the
//							dates of all reports.
//
//		This is written so it works back to OS X 10.2, or at least gracefully
//		fails by just doing nothing on such older OSs. This also should never
//		throw exceptions or anything on failure. This is an additional service
//		for the developer and *mustn't* interfere with regular operation of the
//		application.

"CFBundleExecutable""~/Library/Logs/CrashReporter/"".crash.log""UKCrashReporterLastCrashReportDate"// We have a crash log file and its mod date? Means we crashed sometime in the past.

			// If we never before reported a crash or the last report lies before the last crash:
