 @chapter Command line invocation
 
+@section Quick start
+
+@example
+usage: tcc [-c] [-o outfile] [-bench] [-Idir] [-Dsym[=val]] [-Usym]

+@end example
+
+TCC options are a very much like gcc. The main difference is that TCC
+can also execute directly the resulting program and give it runtime
+arguments.
+
+Here are some examples to understand the logic:
+
+@table @code
+@item tcc a.c
+Compile a.c and execute it directly
+
+@item tcc a.c arg1
+Compile a.c and execute it directly. arg1 is given as first argument to
+the @code{main()} of a.c.
+
+@item tcc -- a.c b.c -- arg1
+Compile a.c and b.c, link them together and execute them. arg1 is given
+as first argument to the @code{main()} of the resulting program. Because
+multiple C files are specified, @code{--} are necessary to clearly separate the
+program arguments from the TCC options.
+
+@item tcc -o myprog a.c b.c
+Compile a.c and b.c, link them and generate the executable myprog.
+
+@item tcc -o myprog a.o b.o
+link a.o and b.o together and generate the executable myprog.
+
+@item tcc -c -o a.o a.c
+Compile a.c and generate object file a.o
+
+@end table
+
+Scripting:
+
+TCC can be invoked from @emph{scripts}, just as shell scripts. You just
+need to add @code{#!/usr/local/bin/tcc} at the start of your C source:
+
 @example
-usage: tcc [-Idir] [-Dsym[=val]] [-Usym] [-llib] [-g] [-b]
-           [-i infile] infile [infile_args...]
+#!/usr/local/bin/tcc
+#include <stdio.h>

+int main() 
+{
