+     "The package provides macros holding file name information (directory,
+base name, extension, full name and full path) for files read by LaTeX
+@code{\\input} and @code{\\include} macros; it uses the file hooks provided by
+the author's @code{filehook}.  In particular, it restores the parent file name
+after the trailing @code{\\clearpage} of an @code{\\included} file; as
+a result, the macros may be usefully employed in the page header and footer of
+the last printed page of such a file.  The depth of inclusion is made
+available, together with the parent (including file) and parents (all
+including files to the root of the tree).  The package supersedes FiNK.")
