Nameless language

Simple brainfuck derivative, here's the Esolangs wiki entry.

Command	Short	Action
0000	>	Move pointer to the right.
0001	<	Move pointer to the left.
0010	+	Incriment value under pointer.
0011	-	Decrement value under pointer.
0100	.	Output current value as ascii.
0101	,	Ask the user for input as ascii.
0110	[	If the byte under the pointer is zero, jump the pointer forward to the next matching 0111 command.
0111	]	If the byte under the pointer is zero, jump the pointer back to the matching 0110 command.
1000	a	Adds the number represented in binary of the next command.
1001	s	Subtracts the number represented in binary of the next command.
1010	r	Sets the current cell to either 1 or 0.
1011	c	Resets the current cell to value 0.
1100	p	Resets the pointer to 0.

Interpreter

Additionally to being able to parse strings of 0s and 1s the interpreter is also able to parse shortcuts for these (see the above table) and parsing half-bytes as described above from raw bytestrings. These three modes (Shortcuts, Normal and Bytestrings) can be used for either reading the source or translating another format to that one (-t flag).

usage: nameless (-e expr | file) [-b | -s] [-i file] [-t (S|N|B)]
  -e         --expr          supply source via command
  -b         --bytes         read source as bytestream
  -s         --short         use shortcuts in source
  -i file    --input=file    read inputs from file
  -t format  --trans=format  translate shortcuts
  -v         --verbose       print debug information

Example

Hello, World!

The following program prints Hello, World!:

001001100011001100000011011000000000001000000011001100110011001100010001011100010011001100010011001100110111000000110100000000000000001001000000000001000100001000100010011001000000011100010001000100010100001000100010010000110011001100110011001101000001000100110100000000000000000000100100
