‘just’ is command-oriented, not target-oriented; this allows you to have:

- two ways of producing the same file

- a command with no side effects

- not having to draw up a state machine

just can enumerate its own commands, which is minor but helpful

just can execute in multiple directories, and can descend directories

just treats spaces and tabs identically for indention, rather than space-indented for shell scripts and tab-indented for make commands
