Usage: $PROGNAME [all] [checkout] [ftp <URL> [diff] [test] [srcdir] [release] [help]
	[clean] [distclean] [echo] [deploy <dir>] [deploydir <dir>]
	[zlib <zlib_path>] [releasedir <dir>] [srcdirname <dir>] [check-vfd]
	[exec <command>] [module-load <module-list>] [op-configure <option>] 
        [--<option>]
    all:      Run all commands (checkout, test & release)
              [Default is all]
    checkout: Run source checkout
    diff:     Run diff on current and previous versions.  Exit 0 if
              no significant differences are found.  Otherwise, non-zero.
    deploy:   deploy binary to directory <dir>
    deploydir: use <dir> as the default directory for deployment
    test:     Run test
    release:  Run release
    clean:    Run make clean
    distclean:Run make distclean
    echo:     Turn on echo mode (set -x)
    setenv <name> <value>:
              Set environment variable <name> to <value>.
    setenvN <N> <name> <value> ...:
	      Set environment variable with <N> values.
	      E.g., setenvN 3 x a b c is same as setenv x="a b c".
    srcdir:   Use srcdir option (does not imply other commands)
              "snapshot srcdir" is equivalent to "snapshot srcdir all"
              "snapshot srcdir checkout" is equivalent to "snapshot checkout"
    srcdirname <dir>:
              Use <dir> as the srcdir testing directory if srcdir is choosen.
              If <dir> starts with '-', it is append to the default name
              E.g., "snapshot srcdir srcdirname -xx" uses hostname-xx
              [Default is hostname]
    help:     Print this message
    echo:     Turn on shell echo
    zlib <zlib_path>:
              Use <zlib_path> as the ZLIB locations
              [Default is $ZLIB_default]
    releasedir <dir>:
              Use <dir> as the release directory
              [Default is $ReleaseDir_default]
    check-vfd:
	      Run make check-vfd instead of just make check.
    exttest <testscript>;
              Run testscript;
    exec <command>:
              Run <command>;
    module-load <module-list>:
              Load modules in comma-separated <module-list>;
    op-configure <option>:
              Pass <option> to the configure command
              E.g., "snapshot op-configure --enable-parallel"
                  configures for parallel mode
    --<option>:
              Pass --<option> to the configure command
              E.g., "snapshot --enable-parallel"
                  configures for parallel mode
