(".")


Documentation:
A list of directories that gud jdb should search for source code.
The file names should be absolute, or relative to the current
directory.

The set of .java files residing in the directories listed are
syntactically analyzed to determine the classes they define and the
packages in which these classes belong. In this way gud jdb maps the
package-qualified class names output by the jdb debugger to the source
file from which the class originated. This allows gud mode to keep
the source code display in sync with the debugging session.
