Hi David, I made this patch to port the improvements you made to 2.7.  The new usage message looks like this:

usage: python compileall.py [-l] [-f] [-q] [-d destdir] [-x regexp] [-i list] [directory|file ...]

arguments: zero or more file and directory names to compile; if no arguments given, 
           defaults to the equivalent of -l sys.path

options:
-l: don't recurse into subdirectories
-f: force rebuild even if timestamps are up-to-date
-q: output only error messages
-d destdir: directory to prepend to file paths for use in compile-time tracebacks and in
            runtime tracebacks in cases where the source file is unavailable
-x regexp: skip files matching the regular expression regexp; the regexp is searched for
           in the full path of each file considered for compilation
-i file: add all the files and directories listed in file to the list considered for
         compilation; if "-", names are read from stdin

I noticed some minor style issues, so I (IMO) improved them in my 2.7 patch and made a 3.x patch with the same minor touch-ups.
