-"""Compatibility code for handling string/bytes changes from Python 2.x to Py3k
-
-In Python 2.x, strings (of type ''str'') contain binary data, including encoded
-Unicode text (e.g. UTF-8). The separate type ''unicode'' holds Unicode text.
-Unicode literals are specified via the u'...' prefix. Indexing or slicing
-either type always produces a string of the same type as the original.
-Data read from a file is always of '''str'' type.
-
-In Python 3.x, strings (type ''str'') may only contain Unicode text. The u'...'
-prefix and the ''unicode'' type are now redundant. A new type (called
-''bytes'') has to be used for binary data (including any particular
-''encoding'' of a string). The b'...' prefix allows one to specify a binary
-literal. Indexing or slicing a string produces another string. Slicing a byte
-string produces another byte string, but the indexing operation produces an
-integer. Data read from a file is of '''str'' type if the file was opened in
-text mode, or of ''bytes'' type otherwise.
-
-Since PyCrypto aims at supporting both Python 2.x and 3.x, the following helper
-functions are used to keep the rest of the library as independent as possible
-from the actual Python version.
-
-In general, the code should always deal with binary strings, and use integers
-instead of 1-byte character strings.
-
-b(s)
- Take a text string literal (with no prefix or with u'...' prefix) and
- make a byte string.
-bchr(c)
- Take an integer and make a 1-character byte string.
-bord(c)
- Take the result of indexing on a byte string and make an integer.
-tobytes(s)
- Take a text string, a byte string, or a sequence of character taken from
- a byte string and make a byte string.
