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
sys.path.
Recursively descend the directory tree named by dir, compiling
all .py files along the way. The maxlevels parameter
is used to limit the depth of the recursion; it defaults to
10. If ddir is given, it is used as the base path from
which the filenames used in error messages will be generated.
Byte-compile all the .py files found along sys.path.
If skip_curdir is true (the default), the current directory is
not included in the search. The maxlevels parameter defaults
to 0 and is passed to the compile_dir() function.
