\modulesynopsis{Tools for byte-compiling all Python source files in a
directory tree.}


This module provides some utility functions to support installing
Python libraries.  These functions compile Python source files in a
directory tree, allowing users without permission to write to the
libraries to take advantage of cached byte-code files.

The source file for this module may also be used as a script to
compile Python sources in directories named on the command line or in
\code{sys.path}.


\begin{funcdesc}{compile_dir}{dir\optional{, maxlevels\optional{, ddir}}}
  Recursively descend the directory tree named by \var{dir}, compiling
  all \file{.py} files along the way.  The \var{maxlevels} parameter
  is used to limit the depth of the recursion; it defaults to
  \code{10}.  If \var{ddir} is given, it is used as the base path from 
  which the filenames used in error messages will be generated.
\end{funcdesc}

\begin{funcdesc}{compile_path}{\optional{skip_curdir\optional{, maxlevels}}}
  Byte-compile all the \file{.py} files found along \code{sys.path}.
  If \var{skip_curdir} is true (the default), the current directory is 
  not included in the search.  The \var{maxlevels} parameter defaults
  to \code{0} and is passed to the \function{compile_dir()} function.
\end{funcdesc}
