+
+ However, if a Python installation is shared between users, it is a
+ good idea to byte-compile all modules upon installation, since
+ other users may not be able to write in the source directories,
+ and thus they won't be able to write the .pyc/.pyo file, and then
+ they would be byte-compiling every module each time it is loaded.
+ This can slow down program start-up considerably.

+ See compileall.py for a script/module that uses this module to
