+Rip — a stack-based rip language
+=================================
+
+All stack items are signed bigints.
+
+- `0-9`: push value
+- `P`: pop
+- `S`: swap
+- `D`: duplicate
+- `i`: increment
+- `d`: decrement
+- `r`: pops the number of items to rotate anti-clockwise
+- `R`: pops the number of items to rotate clockwise
+- `l`: push length of stack (before this push)
+- `a` `s` `m` `q` `M` `p`: `+` `-` `*` `/` `%` `^` (add, subtract, multiply, quotient (integer), modulo, power)
+- `G` `L` `E`: greater, less, equal; booleans are 1 and 0, as you expect
+- `n`: not; equivalent to 0E
+- `[ ... ]`: syntactical; a codeblock
+- `I`: pops boolean, conditionally executing the codeblock that should follow the I, depending on the boolean (aka "if")
+- `W`: I, but then "while" instead of "if"
+- `o`: outputs the top value as an ascii char
+- `O`: outputs the top value as a number
+- `g`: gets a character and pushes the ascii value
+- `F<bla>[code]`: define a function named "bla" with the body "code"
+- `<bla>`: call the function named "bla"
+- `$`: outputs a stackdump
+- whitespace: nop
+- `'c`: pushes the ascii value of c
+- `#<file.rip>`: literally includes contents of 'file.rip' in-place
+
+
+Any error causes the interpreter to exit, saying "rip".
