+=head1 NAME
+
+llvm-extract - extract a function from an LLVM module
+
+=head1 SYNOPSIS
+
+B<llvm-extract> [I<options>] B<--func> I<function-name> [I<filename>]
+
+=head1 DESCRIPTION
+
+The B<llvm-extract> command takes the name of a function and extracts it from
+the specified LLVM bitcode file. It is primarily used as a debugging tool to
+reduce test cases from larger programs that are triggering a bug.
+
+In addition to extracting the bitcode of the specified function,
+B<llvm-extract> will also remove unreachable global variables, prototypes, and
+unused types.
+
+The B<llvm-extract> command reads its input from standard input if filename is
+omitted or if filename is -. The output is always written to standard output,
+unless the B<-o> option is specified (see below).
+
+=head1 OPTIONS
+
+=over
+
+=item B<-f>
+
+Enable binary output on terminals. Normally, B<llvm-extract> will refuse to
+write raw bitcode output if the output stream is a terminal. With this option,
+B<llvm-extract> will write raw bitcode regardless of the output device.
+
+=item B<--func> I<function-name>
+
+Extract the function named I<function-name> from the LLVM bitcode.
+
+=item B<--help>
+
+Print a summary of command line options.
+
+=item B<-o> I<filename>
+
+Specify the output filename. If filename is "-" (the default), then
+B<llvm-extract> sends its output to standard output.
+
+=item B<-S>
+
+Write output in LLVM intermediate language (instead of bitcode).
+

+
+=head1 EXIT STATUS
+
+If B<llvm-extract> succeeds, it will exit with 0. Otherwise, if an error
+occurs, it will exit with a non-zero value.
