  13 The \module{py_compile} module provides a single function to generate
  14 a byte-code file from a source file.
  15
  16 Though not often needed, this function can be useful when installing
  17 modules for shared use, especially if some of the users may not have
  18 permission to write the byte-code cache files in the directory
  19 containing the source code.

  22 \begin{funcdesc}{compile}{file\optional{, cfile\optional{, dfile}}}
  23   Compile a source file to byte-code and write out the byte-code cache
  24   file.  The source code is loaded from the file name \var{file}.  The
  25   byte-code is written to \var{cfile}, which defaults to \var{file}
  26   \code{+} \code{'c'} (\code{'o'} if optimization is enabled in the
  27   current interpreter).  If \var{dfile} is specified, it is used as
  28   the name of the source file in error messages instead of \var{file}.
