Documentation and extraction for packages and document classes
Description
The class provides the functionality and implementation of
packages and document classes. It is loosely based on the ydoc
and ltxdoc classes, but has a number of incompatible
differences. The class defines a MacroCode environment which
offers an alternative to the the usual docstrip method of
installing packages. It has the ability to generate both
documentation and code in a single run of a single file.
