+Delvs
+=====
+
+Delvs(Pronounced Del-vis) is my own personal variation of brainfuck, the interpreter is written in C.
+File reading was inspired by brainfuck++, and the bit fiddling was inspired by boolfuck(DuckDuckGo them if you have to, I'm not putting links there right now)
+
+Additions
+---------
+- `:` casts the current value to a string and prints it. Code: `printf("%hhd", *p);`
+- `;` grabs value from user input and casts to cell value. Code: `scanf("%hhd", p);`
+- `#` reads following cells as null-terminating string for filename, then if current cell is != 1, open file for reading, or if 1, open file writing. Code: `f = fopen(p + 1, p == 1 ? "w" : "r");`
+- `` ` `` read next char from file, apply to current cell. (`EOF` becomes `0`) Code: `*p = fgetc(f);`
+- `!` write char from current cell to file. Code: `fputc(*p, f);`
+- `"` increment current bit position by 1. (psuedo)Code: `b++;`
+- `'` flip bit at current bit position, then incrment current bit position by 1. Code: `*p ^= (1 << b)`
+- `\ ...` ignore EVERYTHING until newline is reached. `while(*c) if(*c++ == '\') return;`
+- `@` prints value of current cell and surrounding 4 cells. Code:
+- `$` sleeps the current cell's value in seconds
+
+### To do
+- implement a working socket system
+- implement an stdout flushing system
+- implement runtime args
+- implement namespaces(seperate arrays of 30000 chars)
+- (maybe) implement better way to divide
+- implement full integers
+
+Examples
+--------
+Setting entire cell values with just the bit intructions is as easy as converting 0's to `"`s and 1's to `'`s.
+
+    01001000 = 72
+    "'""'""" . >
+    01101001 = 105
+    "''"'""' .
+
+Block comments are very straight forward to use, just plant a `\[` when you start "commenting" and a `]` when you're done.
+
+    +++++ +++++ [
+      > +++++ ++
+      > +++++ +++++
+      \ This is a well placed comment. See, all these code intrustions aren't messing with the program unlike vanilla Brainfuck

+
+How about reading files? Just generate a string as the filename an the use a `#` at the beginning of it. Like so:
+
+    01101101 m
+    "''"''"'
+    01111001 y
+    "''''""'
+    01110100 t
+    "'''"'""
+    01100101 e
+    "''""'"'
+    01111000 x
+    "''''"""
+    01110100 t
+    "'''"'""
+    01100110 f
+    "''""''"
+    01101001 i
+    "''"'""'
+    01101100 l
+    "''"''""
+    01100101 e
+    "''""'"'
+    00101110\.
+    ""'"'''"
+    01110100 t
+    "'''"'""
+    01111000 x
+    "''''"""
+    01110100 t
+    "'''"'""
+
+    [<] #
+    \ standard concatenation loop with file reading(and EOF check)
+    `+[-.`+]
+
+Want to give the actual value of the cell when printing? Just add a dot above your intruction!
+
+    01100100 \ 'd' or 100
+    "''""'""
+
+    . \ prints "d"
+    : \ prints "100"
