* command.h - the CMD structure and routines to manipulate them
*
* Both ACTION and CMD contain a rule, targets, and sources. An
* ACTION describes a rule to be applied to the given targets and
* sources; a CMD is what actually gets executed by the shell. The
* differences are due to:
*
* ACTIONS must be combined if 'actions together' is given.
* ACTIONS must be split if 'actions piecemeal' is given.
* ACTIONS must have current sources omitted for 'actions updated'.
