The package tag indicates the package for which the description file contains documentation. A package is a collection of units which are logically grouped together (for a library, program, component suites). The name attribute of the package tag will be used to select the package node in the description file: Only the package node with name as specified by the package command-line option will be used when generating documentation. All other package nodes will be ignored.
The package node must always reside in a fpdoc-description node. It can contain a descr node, and various module nodes, one node per unit in the package.
