set ::USAGE_MESSAGE {
This Tcl script is used to test the various configurations required
before releasing a new version. Supported command line options (all
optional) are:

    --buildonly                        (Just build testfixture - do not run)
    --config   CONFIGNAME              (Run only CONFIGNAME)
    --dryrun                           (Print what would have happened)
    -f|--force                         (Run even if uncommitted changes)
    --info                             (Show diagnostic info)
    --jobs     N                       (Use N processes - default 1)
    --keep                             (Delete no files after each test run)
    --msvc                             (Use MSVC as the compiler)
    --platform PLATFORM                (see below)
    --progress                         (Show progress messages)
    --quick                            (Run "veryquick.test" only)
    --veryquick                        (Run "make smoketest" only)
    --with-tcl=DIR                     (Use TCL build at DIR)

The script determines the default value for --platform using the
$tcl_platform(os) and $tcl_platform(machine) variables.  Supported
platforms are "Linux-x86", "Linux-x86_64", "Darwin-i386",
"Darwin-x86_64", "Windows NT-intel", and "Windows NT-amd64".

Every test begins with a fresh run of the configure script at the top
of the SQLite source tree.
