+=head1 NAME
+
+stkrc - Stacker Compiler
+
+=head1 SYNOPSIS
+
+B<stkrc> [I<options>] [I<filename>]
+
+=head1 DESCRIPTION
+
+The B<stkrc> command is the compiler for the Stacker language. Stacker is a
+simple stack based, Forth-like language that was written as a demonstration
+language for LLVM. For details on the language, please see
+L<http://llvm.cs.uiuc.edu/docs/Stacker.html> . The B<stkrc> compiler is fairly 
+minimal. It compiles to bytecode only and doesn't perform any optimizations.
+The output of stkrc (a bytecode file) can be piped through other LLVM tools
+for optimization and linking.
+
+If F<filename> is omitted or is C<->, then B<stkrc> reads its input 
+from standard input. This is useful for combining the tool into a pipeline.
+
+If an output file is not specified with the B<-o> option, then
+B<llvm-as> sends its output to a file or standard output by following
+these rules:
+
+=over 
+
+=item *
+
+If the input is standard input, then the output is standard output.
+
+=item *
+
+If the input is a file that ends with C<.st>, then the output file is of
+the same name, except that the suffix is changed to C<.bc>.
+
+=item *
+
+If the input is a file that does not end with the C<.st> suffix, then the
+output file has the same name as the input file, except that the C<.bc>
+suffix is appended.
+

+
+=head1 OPTIONS
+
+=over
+
+=item B<-o> F<filename>
+
+Specify the output file name.  If F<filename> is C<->, then B<llvm-as>
+sends its output to standard output.
+
+=item B<-stats>
+
+Print statistics acquired during compilation.
+
+=item B<-time-passes>
+
+Record the amount of time needed for each pass and print it to standard
+error.
+
+=item B<-f>
+
+Force the output to be written. Normally, B<stkrc> won't overwrite an existing
+bytecode file. This option overrides that behavior. 
+
+=item B<-s=stacksize>
+
+Specify the stack size for the program. The default stack size, 1024, should be
+sufficient for most programs. For very large, programs, you might want to
+provide a larger value.
+
+=item B<-help>
+
+Print a summary of command line options.
+
+=back
+
+=head1 EXIT STATUS
+
+If B<stkrc> succeeds, it will exit with 0.  Otherwise, if an error
+occurs, it will exit with a non-zero value, usually 1.
