@section Option summary
General Options:
@c man begin OPTIONS
@table @option
@item -c
Generate an object file.
@item -o outfile
Put object file, executable, or dll into output file @file{outfile}.
@item -run source [args...]
Compile file @var{source} and run it with the command line arguments
@var{args}. In order to be able to give more than one argument to a
script, several TCC options can be given @emph{after} the
@option{-run} option, separated by spaces:
@example
tcc "-run -L/usr/X11R6/lib -lX11" ex4.c
@end example
In a script, it gives the following header:
#ifdef ONE_SOURCE
#include "libtcc.c"
#else
#include "tcc.h"
