3.21 compileall -- Byte-compile Python libraries.

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.

compile_dir (dir[, maxlevels[, ddir]])

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.

compile_path ([skip_curdir[, maxlevels]])

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.
