- If you run "clean" first, then "build", then "install", the install would not happen
- If you run "clean" first, then "install", luckmake will do "build" then "install"
- this is because "build" is marked runned is the first run.
- it's important to select NCR / TSSR carefully. 
- use NCR when the output cannot be cached. This is true for any command-like rule
- use TSSR or other stamped rule when the output is one or more files.
