+=head1 NAME
+
+llvm-bcanalyzer - LLVM bytecode analyzer
+
+=head1 SYNOPSIS
+
+llvm-bcanalyzer [options] [filename]
+
+=head1 DESCRIPTION
+
+The B<llvm-bcanalyzer> command is a small utility for analyzing bytecode files.
+The tool reads a bytecode file (such as generated with the B<llvm-as> tool) and
+produces a statistical report on the contents of the byteocde file.  The tool
+will also dump a low level but human readable version of the bytecode file. 
+This tool is probably not of much interest or utility except for those working 
+directly with the bytecode file format. Most LLVM users can just ignore
+this tool.
+
+If F<filename> is omitted or is C<->, then B<llvm-bcanalyzer> reads its input 
+from standard input. This is useful for combining the tool into a pipeline.
+
+Output is written to the standard output.
+
+=head1 OPTIONS
+
+=over
+
+=item B<-nodetails>
+
+Causes B<llvm-bcanalyzer> to abbreviate its output by writing out only a module 
+level summary. The details for individual functions are not displayed.
+
+=item B<-dump>
+
+Causes B<llvm-bcanalyzer> to dump the bytecode in a human readable format. This 
+format is significantly different from LLVM assembly and provides details about 
+the encoding of the bytecode file. 
+
+=item B<-verify>
+
+Causes B<llvm-bcanalyzer> to verify the module produced by by reading the 
+bytecode. This ensures that the statistics generated are based on a consistent
+module.
+
+=item B<--help>
+
+Print a summary of command line options.
+
+=back
+
+=head1 EXIT STATUS
+
+If B<llvm-bcanalyzer> succeeds, it will exit with 0.  Otherwise, if an error
+occurs, it will exit with a non-zero value, usually 1.
