+:mod:`py_compile` --- Compile Python source files
+=================================================
+
+.. module:: py_compile
+ :synopsis: Generate byte-code files from Python source files.
+
+.. % Documentation based on module docstrings, by Fred L. Drake, Jr.
+.. % <fdrake@acm.org>
+
+
+
+.. index:: pair: file; byte-code
+
+The :mod:`py_compile` module provides a function to generate a byte-code file
+from a source file, and another function used when the module source file is
+invoked as a script.
+
+Though not often needed, this function can be useful when installing modules for
+shared use, especially if some of the users may not have permission to write the
+byte-code cache files in the directory containing the source code.
+
+
+.. exception:: PyCompileError
+
+ Exception raised when an error occurs while attempting to compile the file.
+
+
+.. function:: compile(file[, cfile[, dfile[, doraise]]])
+
+ Compile a source file to byte-code and write out the byte-code cache file. The
+ source code is loaded from the file name *file*. The byte-code is written to
+ *cfile*, which defaults to *file* ``+`` ``'c'`` (``'o'`` if optimization is
+ enabled in the current interpreter). If *dfile* is specified, it is used as the
+ name of the source file in error messages instead of *file*. If *doraise* is
+ true, a :exc:`PyCompileError` is raised when an error is encountered while
+ compiling *file*. If *doraise* is false (the default), an error string is
+ written to ``sys.stderr``, but no exception is raised.
+
+
+.. function:: main([args])
+
+ Compile several source files. The files named in *args* (or on the command
+ line, if *args* is not specified) are compiled and the resulting bytecode is
+ cached in the normal manner. This function does not search a directory
+ structure to locate source files; it only compiles files named explicitly.
+
+When this module is run as a script, the :func:`main` is used to compile all the
+files named on the command line.
+

+
+ Module :mod:`compileall`
+ Utilities to compile all Python source files in a directory tree.
