.SH NAME
|
|
mcpp \- Matsui CPP, an alternative C preprocessor
|
|
.SH SYNOPSIS
|
|
mcpp [\fIoptions\fP] [\fI<infile>\fP [\fI<outfile>\fP]]
|
|
.SH DESCRIPTION
|
|
\fBmcpp\fR is a C/C++ preprocessor with the highest conformance which implements C90, C99 and C++98.
|
|
\fBmcpp\fR has plentiful diagnostics and many #pragmas.
|
|
It is useful to check portability of your program, and also useful to debug complicated macro.
|
|
This is a man-page for \fBmcpp\fR of compiler-independent-build.
|
|
.SH OPTIONS
|
|
\fBmcpp\fR expects two file names as arguments, \fI<infile>\fR and
|
|
\&\fI<outfile>\fR. If not specified, \fI<infile>\fR defaults to standard input
|
|
and \fI<outfile>\fR defaults to standard output.
|
|
.PP
|
|
It takes the following options.
