NAME

       cxref-cpp - A modified C preprocessor to use with cxref.

SYNOPSIS

       cxref-cpp ...

DESCRIPTION

       To  improve the output that is available for the source code for cross-
       referencing a modified version of the GNU CPP v2.7.2 is supplied (named
       cxref-cpp).

       This  modified  C  preprocessor  allows  for  a finer control over some
       features of the preprocessing that are not important  for  a  compiler.
       In  a  standard  preprocessor, the preprocessor directives are intended
       for use only by the preprocessor, so passing the information through is
       not important.

       With  cxref-cpp,  there  are  some  features  that are different to the
       standard GNU CPP:

              Compared to gcc versions earlier than version 2.8.0 there is  an
              extra option that will output the #include lines from the source
              file.  In version 2.8.0 and later this option is present.

              Comments trailing a #include or a #define are not  preserved  by
              all  versions of gcc even if the -C option is used.  This is not
              important while compiling, but is useful for documenting.

              The cxref-cpp program  will  take  on  the  personality  of  the
              installed  version  of  gcc  so that the gcc header files can be
              parsed.  This means that it includes the  same  default  include
              directory  paths  and macro definitions.  The file that contains
              these definitions is called cxref-cpp.defines and  is  installed
              by  the  cxref-cpp-configure program or specified by the -cxref-
              cpp-defines command line option.

OPTIONS

       The same as for gcc, apart from ’-cxref-cpp-defines’ described above.
