"""Module/script to "compile" all .py files to .pyc (or .pyo) file.
|
|
|
|
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.
