+ Note that it isn't necessary to byte-compile Python modules for
+ execution efficiency -- Python itself byte-compiles a module when
+ it is loaded, and if it can, writes out the bytecode to the
+ corresponding .pyc file.
+
+ 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 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
+ byte-compile all installed files (or all files in selected
+ directories).
+
+ Do note that FileExistsError is raised if cfile ends up pointing at a
+ non-regular file or symlink. Because the compilation uses a file renaming,
+ the resulting file would be regular and thus not the same type of file as
