+llvm-bcanalyzer - LLVM bitcode analyzer
=head1 SYNOPSIS
-B<llvm-bcanalyzer> [I<options>] [I<filename>]
+B<llvm-bcanalyzer> [I<options>] [F<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.

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.
