Usage: pyrexc [options] sourcefile...
Options:
-v, --version Display version number of pyrex compiler
-l, --create-listing Write error messages to a listing file
-I, --include-dir <directory> Search for include files in named directory
-o, --output-file <filename> Specify name of generated C file
-r, --recursive Recursively find and compile dependencies
-t, --timestamps Only compile newer source files (implied with -r)
-f, --force Compile all source files (overrides implied -t)
-q, --quiet Don't print module names in recursive mode
The following experimental options are supported only on MacOSX:
-C, --compile Compile generated .c file to .o file
-X, --link Link .o file to produce extension module (implies -C)
-+, --cplus Use C++ compiler for compiling and linking
Additional .o files to link may be supplied when using -X."""
