 =head1 DESCRIPTION
 
 The B<opt> command is the modular LLVM optimizer and analyzer.  It takes LLVM 
-bytecode as input, runs the specified optimizations or analyses on it, and then
-outputs the optimized LLVM bytecode or the analysis results.  The function of 
+bitcode as input, runs the specified optimizations or analyses on it, and then
+outputs the optimized LLVM bitcode or the analysis results.  The function of 
 B<opt> depends on whether the B<-analyze> option is given. 
 
 When B<-analyze> is specified, B<opt> performs various analyses of LLVM 
-bytecode.  It will usually print the results on standard output, but in a few 
+bitcode.  It will usually print the results on standard output, but in a few 
 cases, it will print output to standard error or generate a file with the 
 analysis output, which is usually done when the output is meant for another 
 program.  
 
 While B<-analyze> is I<not> given, B<opt> attempts to produce an optimized 
-bytecode file.  The optimizations available via B<opt> depend upon what 
+bitcode file.  The optimizations available via B<opt> depend upon what 
 libraries were linked into it as well as any additional libraries that have 
 been loaded with the B<-load> option.  Use the B<-help> option to determine 
 what optimizations you can use.
 
 If I<filename> is omitted from the command line or is I<->, B<opt> reads its
-input from standard input. The input must be an LLVM bytecode file.

 If an output filename is not specified with the B<-o> option, B<opt>
 writes its output to the standard output.
