 ** This module currently supports the following encodings:
 ** uuencode:
-**     	each line encodes 45 bytes (except possibly the last)
-**	First char encodes (binary) length, rest data
-**	each char encodes 6 bits, as follows:
-**	binary: 01234567 abcdefgh ijklmnop
-**	ascii:  012345 67abcd efghij klmnop
-**	ASCII encoding method is "excess-space": 000000 is encoded as ' ', etc.
-**	short binary data is zero-extended (so the bits are always in the
-**	right place), this does *not* reflect in the length.

 ** base64:
 **      Line breaks are insignificant, but lines are at most 76 chars
 **      each char encodes 6 bits, in similar order as uucode/hqx. Encoding
 **      is done via a table.
 **      Short binary data is filled (in ASCII) with '='.
 ** hqx:
-**	File starts with introductory text, real data starts and ends
-**	with colons.
-**	Data consists of three similar parts: info, datafork, resourcefork.
-**	Each part is protected (at the end) with a 16-bit crc
-**	The binary data is run-length encoded, and then ascii-fied:
-**	binary: 01234567 abcdefgh ijklmnop
-**	ascii:  012345 67abcd efghij klmnop
-**	ASCII encoding is table-driven, see the code.
-**	Short binary data results in the runt ascii-byte being output with
-**	the bits in the right place.

 ** While I was reading dozens of programs that encode or decode the formats
 ** here (documentation? hihi:-) I have formulated Jansen's Observation:
 **
-**	Programs that encode binary data in ASCII are written in
-**	such a style that they are as unreadable as possible. Devices used
-**	include unnecessary global variables, burying important tables
-**	in unrelated sourcefiles, putting functions in include files,
-**	using seemingly-descriptive variable names for different purposes,
-**	calls to empty subroutines and a host of others.
