-    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

-              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"

-              Use <dir> as the srcdir testing directory if srcdir is choosen.

-              E.g., "snapshot srcdir srcdirname -xx" uses hostname-xx

-              Run make check-vfd instead of just make check.
-    check-passthrough-vol:
-              Run make check-passthrough-vol instead of just make check.
-              NOTE: Will only succeed with passthrough VOL connectors
