- """Byte-compile one Python source file to Python bytecode.
-
- Arguments:
-
- file: source filename
- cfile: target filename; defaults to source with 'c' or 'o' appended
- ('c' normally, 'o' in optimizing mode, giving .pyc or .pyo)
- dfile: purported filename; defaults to source (this is the filename
- that will show up in error messages)
-
- 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 (or .pyo) 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/.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
- byte-compile all installed files (or all files in selected
- directories).
