/**
* This package contains a number of classes that assists by analyzing JARs and
* constructing bundles. The Analyzer class can be used to analyze an existing
* bundle and can create a manifest specification from proposed (wildcard)
* Export-Package, Bundle-Includes, and Import-Package headers. The Builder
* class can use the headers to construct a JAR from the classpath. The Verifier
* class can take an existing JAR and verify that all headers are correctly set.
* It will verify the syntax of the headers, match it against the proper
* contents, and verify imports and exports. A number of utility classes are
* available. Jar, provides an abstraction of a Jar file. It has constructors
* for creating a Jar from a stream, a directory, or a jar file. A Jar, keeps a
* collection Resource's. There are Resource implementations for File, from
* ZipFile, or from a stream (which copies the data). The Jar tries to minimize
* the work during build up so that it is cheap to use. The Resource's can be
* used to iterate over the names and later read the resources when needed.
* Clazz, provides a parser for the class files. This will be used to define the
* imports and exports. Headers are translated to
* {@link aQute.bnd.header.Parameters Parameter} that contains all headers (the
* order is maintained). The attribute of each header are maintained in an
* {@link aQute.bnd.header.Attrs Attrs}. Each additional file in a header
* definition will have its own entry (only native code does not work this way).
* The ':' of directives is considered part of the name. This allows attributes
* and directives to be maintained in the Attributes map. An important aspect of
* the specification is to allow the use of wildcards. Wildcards select from a
* set and can decorate the entries with new attributes. This functionality is
* implemented in Instructions. Much of the information calculated is in
* packages. A package is identified by a PackageRef (and a type by a TypeRef).
* The namespace is maintained by {@link Descriptors}, which here is owned by
* {@link Analyzer}. A special class, {@link Packages} maintains the attributes
* that are found in the code. @version $Revision: 1.2 $
