 llvm-extract - extract a function from an LLVM module
 =====================================================
 
-
 SYNOPSIS
 --------
 
-
-**llvm-extract** [*options*] **--func** *function-name* [*filename*]
-
+:program:`llvm-extract` [*options*] **--func** *function-name* [*filename*]
 
 DESCRIPTION
 -----------
 
-
-The **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.
+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,
-**llvm-extract** will also remove unreachable global variables, prototypes, and
-unused types.
-
-The **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).
+: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, **llvm-extract** will refuse to
- write raw bitcode output if the output stream is a terminal. With this option,
- **llvm-extract** will write raw bitcode regardless of the output device.

 **-help**
 
  Print a summary of command line options.

 **-S**
 
  Write output in LLVM intermediate language (instead of bitcode).
