+llvm-extract - extract a function from an LLVM module
+=====================================================
+
+SYNOPSIS
+--------
+
+:program:`llvm-extract` [*options*] **--func** *function-name* [*filename*]
+
+DESCRIPTION
+-----------
+
+The :program:`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,
+:program:`llvm-extract` will also remove unreachable global variables,
+prototypes, and unused types.
+
+The :program:`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 **-o** option is specified (see below).
+
+OPTIONS
+-------
+
+**-f**
+
+ Enable binary output on terminals.  Normally, :program:`llvm-extract` will
+ refuse to write raw bitcode output if the output stream is a terminal.  With
+ this option, :program:`llvm-extract` will write raw bitcode regardless of the
+ output device.
+
+**--func** *function-name*
+
+ Extract the function named *function-name* from the LLVM bitcode.  May be
+ specified multiple times to extract multiple functions at once.
+
+**--rfunc** *function-regular-expr*
+
+ Extract the function(s) matching *function-regular-expr* from the LLVM bitcode.
+ All functions matching the regular expression will be extracted.  May be
+ specified multiple times.
+
+**--glob** *global-name*
+
+ Extract the global variable named *global-name* from the LLVM bitcode.  May be
+ specified multiple times to extract multiple global variables at once.
+
+**--rglob** *glob-regular-expr*
+
+ Extract the global variable(s) matching *global-regular-expr* from the LLVM
+ bitcode.  All global variables matching the regular expression will be
+ extracted.  May be specified multiple times.
+
+**-help**
+
+ Print a summary of command line options.
+
+**-o** *filename*
+
+ Specify the output filename.  If filename is "-" (the default), then
+ :program:`llvm-extract` sends its output to standard output.
+
+**-S**
+
+ Write output in LLVM intermediate language (instead of bitcode).
+
+EXIT STATUS
+-----------
+
+If :program:`llvm-extract` succeeds, it will exit with 0.  Otherwise, if an error
+occurs, it will exit with a non-zero value.
