#         This file contains the <code>IncludeHash</code> class.  It is used
#         as a data structure for keeping track of where #include
#         directives appear within a header file.

#     @discussion
#         The <code>IncludeHash</code> class is basically used as a data structure
#         without accessor methods.
#
#         This class stores where a particular #include
#         directive appears within a header file.  Each header
#         file has an array containing one <code>IncludeHash</code>
#         instance for each header that it includes.
#
#     @var FILENAME
#         The filename (and leading path parts) included
#         at a particular line number.
#     @var LINENUM
#         The line number at which the include statement
#         appears.
#     @var HASHREF
#         The <code>HeaderDoc::HeaderFileCPPHashHash</code>
#         hash for the file specified by <code>FILENAME</code>,
#         which in turn comes from the <code>CPP_HASH</code> in
#  {@link //apple_ref/perl/cl/HeaderDoc::BlockParse BlockParse}.
#         This includes the C preprocessor tokens defined by
#         the file in question.
