<answer id="arch-usecases">
<p>
Different technology support modules will supply definitions of different
kinds of libraries, e.g. Java JARs, that may be reused in user projects.
Modules may register library predefinitions to wrap libraries they bundle.
Project type providers can refer to available libraries in customizer dialogs.

<p>
Permits <q>libraries</q> to be defined, customized, and stored by the user for
reuse in multiple projects. For example, a Java JAR library has a classpath
(usually one JAR), and an optional source path and Javadoc path that may be
used for development-time features.
