/** A component manager provides access to the pieces of xsbt that are distributed as components.
|
||
|
|
* There are two types of components. The first type is compiled subproject jars with their dependencies.
|
||
|
|
* The second type is a subproject distributed as a source jar so that it can be compiled against a specific
|
||
|
|
* version of Scala.
|
||
|
|
*
|
||
|
|
* The component manager provides services to install and retrieve components to the local repository.
|
||
|
|
* This is used for source jars so that the compilation need not be repeated for other projects on the same
|
||
|
|
* machine.
