This Tcl script is used to test various configurations of SQLite. By
default it uses "wapp" to provide an interactive interface. Supported 
command line options (all optional) are:

    --platform    PLATFORM         (which tests to run)
    --smoketest                    (run "make smoketest" only)
    --veryquick                    (run veryquick.test only)
    --buildonly                    (build executables, do not run tests)
    --jobs        N                (number of concurrent jobs)
    --tcl         DIR              (where to find tclConfig.sh)
    --deletefiles                  (delete extra files after each test)
    --msvc                         (Use MS Visual C)
    --debug                        (Also run [n]debugging versions of tests)
    --noui                         (do not use wapp)
