 // This file provides reliablity tests which run for ChromeFrame.
 //
 // Usage:
 // <reliability test exe> --list=file --startline=start --endline=end [...]
 // Upon invocation, it visits each of the URLs on line numbers between start
 // and end, inclusive, stored in the input file. The line number starts from 1.
 //
 // Optional Switches:
 // --iterations=num: goes through the list of URLs constructed in usage 2 or 3
 //                   num times.
 // --memoryusage: prints out memory usage when visiting each page.
 // --logfile=filepath: saves the visit log to the specified path.
 // --timeout=seconds: time out as specified in seconds during each
 //                    page load.
 // --nopagedown: won't simulate page down key presses after page load.
 // --noclearprofile: do not clear profile dir before firing up each time.
 // --savedebuglog: save Chrome, V8, and test debug log for each page loaded.
