} -presql {
  pragma mmap_size = 268435456;

  fail under valgrind) omitted.
} -files [
  test_set $allquicktests -exclude *malloc* *ioerr* *fault* wal.test atof1.test

before releasing a new version. Supported command line options (all
optional) are:

    --srcdir   TOP-OF-SQLITE-TREE      (see below)
    --platform PLATFORM                (see below)
    --config   CONFIGNAME              (Run only CONFIGNAME)
    --quick                            (Run "veryquick.test" only)
    --veryquick                        (Run "make smoketest" only)
    --buildonly                        (Just build testfixture - do not run)
    --dryrun                           (Print what would have happened)
    --info                             (Show diagnostic info)

The default value for --srcdir is the parent of the directory holding
this script.

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" and "Darwin-i386".

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