This package contains interfaces related to targets.

A project can create multiple targets to build multiple SWF and/or SWC files. Each target drives one or more (but not necessarily all) of the project's compilation units through their compilation phases, and assembles the resulting ABC or SWF tags into a SWF or SWC. See the `org.apache.royale.compiler.units` package for more information about compilation units.

Some configuration options become project settings, while others become target settings. For example, the source path and library path are project settings, but whether a particular SWC is to be linked internally or externally (that is, whether is "on the external library path") is a target setting.

The base interface for all targets is `ITarget`. There are two different kinds of external targets, each with its own subinterface:

`ISWFTarget` | Builds a SWF file from a set of compilation units.
`ISWCTarget` | Builds a SWC file from a set of compilation units.
