Detailed Description

Action - Represent an abstract compilation step to perform.

An action represents an edge in the compilation graph; typically it is a job to transform an input using some tool.

The current driver is hard wired to expect actions which produce a single primary output, at least in terms of controlling the compilation. Actions can produce auxiliary files, but can only produce a single output to feed into subsequent actions.

Actions are usually owned by a Compilation, which creates new actions via MakeAction().
