dddZdd Zedkree Zee dS )a Module/script to byte-compile all .py files to .pyc files.
When called as a script with arguments, this compiles the directories
given as arguments recursively; the -l option prevents it from
recursing into directories.
Without arguments, if compiles all modules on sys.path, without
recursing into subdirectories. (Even though it should do so for
packages -- for now, you'll have to deal with packages separately.)
See module py_compile for details of the actual byte-compilation.

Arguments (only dir is required):
dir: the directory to byte-compile
maxlevels: maximum recursion level (default 10)
ddir: the directory that will be prepended to the path to the
file as it is compiled into each byte-code file.
force: if True, force compilation, even if timestamps are up-to-date
quiet: full output with False or 0, errors only with 1,
no output with 2
legacy: if True, produce legacy pyc paths instead of PEP 3147 paths
optimize: optimization level or -1 for level of the interpreter
workers: maximum number of parallel workers
invalidation_mode: how the up-to-dateness of the pyc will be checked
