"""Byte-compile a collection of Python source files to .pyc

If 'force' is true, all files are recompiled regardless of

The source filename encoded in each bytecode file defaults to the
filenames listed in 'py_files'; you can modify these with 'prefix' and
'basedir'. 'prefix' is a string that will be stripped off of each
source filename, and 'base_dir' is a directory name that will be
prepended (after 'prefix' is stripped). You can supply either or both
(or neither) of 'prefix' and 'base_dir', as you wish.
If 'dry_run' is true, doesn't actually do anything that would
affect the filesystem.
Byte-compilation is either done directly in this interpreter process
with the standard py_compile module, or indirectly by writing a
temporary script and executing it. Normally, you should let
'byte_compile()' figure out to use direct compilation or not (see
the source for details). The 'direct' flag is used by the script
generated in indirect mode; unless you know what you're doing, leave
it set to None.
