NAME
       h2paspp - Free Pascal h2pas preprocessor program.


SYNOPSIS
       h2paspp [-doih] file1 ... filen


DESCRIPTION
       h2paspp reads one or more C header files and preprocesses them, writing
       the result to files with the same name as the originals as it goes
       along.  It does not accept all preprocesser tokens of C, but takes care
       of the following preprocessor directives:

       #define symbol
              Defines the new symbol symbol. Note that macros are not
              supported.

       #if symbol
              The text following this directive is included if symbol is
              defined.

       #ifdef symbol
              The text following this directive is included if symbol is
              defined.

       #ifndef symbol
              The text following this directive is included if symbol is not
              defined.

       #include filename
              Include directives are removed, unless the -I option was given,
              in which case the include file is included and written to the
              output file.

       #undef symbol
              The symbol symbol is undefined.


USAGE
       h2paspp accepts one or more filenames and preprocesses them. It will
       read the input, and write output to a file with the same name unless
       the -o option is given, in which case the file is written to the
       specified file.  Note that only one output filename can be given.



OPTIONS
       h2paspp has a small number of options to control its behaviour:


       -dsymbol
              Define the symbol symbol before processing is started.

       -h     emit a small helptext.

       -ooutfile
              If this option is given, the output will be written to a file
              named outfile. Note that only one output file can be given.
