+### STATUS: INABIAF - please **DO NOT** fix
+### Source code: [2005/mikeash/mikeash.c](2005/mikeash/mikeash.c)
+### Information: [2005/mikeash/README.md](2005/mikeash/README.md)
+
+The author states:
+
+* The only built-in functions are `defvar`, `format`, `substitute`,
+`char-upcase`, `+`, `-`, `*`, and `/`.
+
+* Only one variable is available. This variable is called `q`, although any
+symbol name starting with the letter `q` will be mapped to this variable.
+
+* Only the first letter of a function name is significant. For example,
+`format`, `f`, `farm`, and various other words starting with `f` will all map to
+the `format` function.
+
+* The `defvar` function completely ignores its first parameter. It will always
+store the result of evaluating its second parameter in `q`. Unlike in [Common
+Lisp](https://en.wikipedia.org/wiki/Common_Lisp), multiple invocations of
+`defvar` on the same variable will overwrite old values.
+
+* Character constants are limited to `#\Newline` and single-character
+constants such as `#\x`.
+
+* The `char-upcase` function will give strange results if passed something
+other than a lowercase character.
+
+* The `format` function takes exactly three parameters. The first parameter is
+ignored; output always goes to `stdout`. The second parameter must have exactly
+one `~s` format specifier in it, and no other format specifiers are permitted.
+
+* The arithmetic functions take exactly two parameters.
+
+* All tokens must be separated from a following `)` by whitespace.
+
+* A lot of other things. Notably, the language which this program interprets is
+nowhere near
+[Turing-complete](https://en.wikipedia.org/wiki/Turing_completeness).
+
+Basically, the [LISP][] interpreter is good for some basic math operations, and
+for running itself.
