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.
