-""" Standard "encodings" Package
-
- Standard Python encoding modules are stored in this package
- directory.
-
- Codec modules must have names corresponding to normalized encoding
- names as defined in the normalize_encoding() function below, e.g.
- 'utf-8' must be implemented by the module 'utf_8.py'.
-
- Each codec module must export the following interface:
-
- * getregentry() -> codecs.CodecInfo object
- The getregentry() API must a CodecInfo object with encoder, decoder,
- incrementalencoder, incrementaldecoder, streamwriter and streamreader
- atttributes which adhere to the Python Codec Interface Standard.
-
- In addition, a module may optionally also define the following
- APIs which are then used by the package's codec search function:
-
- * getaliases() -> sequence of encoding name strings to use as aliases
-
- Alias names returned by getaliases() must be normalized encoding
- names as defined by normalize_encoding().
