   9 This module provides some utility functions to support installing
  10 Python libraries.  These functions compile Python source files in a
  11 directory tree, allowing users without permission to write to the
  12 libraries to take advantage of cached byte-code files.
  13
  14 The source file for this module may also be used as a script to
  15 compile Python sources in directories named on the command line or in
  16 \code{sys.path}.

  21   Recursively descend the directory tree named by \var{dir}, compiling
  22   all \file{.py} files along the way.  The \var{maxlevels} parameter
  23   is used to limit the depth of the recursion; it defaults to
  24   \code{10}.  If \var{ddir} is given, it is used as the base path from
  25   which the filenames used in error messages will be generated.  If
  26   \var{force} is true, modules are re-compiled even if the timestamps
  27   are up to date.

  31                                maxlevels\optional{, force}}}}
  32   Byte-compile all the \file{.py} files found along \code{sys.path}.
  33   If \var{skip_curdir} is true (the default), the current directory is
  34   not included in the search.  The \var{maxlevels} and
  35   \var{force} parameters default to \code{0} and are passed to the
  36   \function{compile_dir()} function.
