Not sure what I just fixed.

Not needed with new GC.

-# SCL: Simple Calculator Language
+# SCL: Simple CAS Language
 
-A spiritual successor to halk.
+*v0.3*
+
+SCL aims to be a human-friendly Computer Algebra System (CAS) inspired by
+[maxima](https://maxima.sourceforge.io/) that feels like writing on paper. In
+its current state, SCL can be used as a functional programming language capable
+of performing simple arithmetic. The codebase is about 2,000 lines of
+handwritten C, including a parser, interpreter, and runtime. It uses a linked
+environment scoping model.
+
+## Usage
+
+To download and run:
+
+```bash
+git clone https://git.signorovitch.org/scl/scl -b stable && cd scl
+make release
+./scl.out
+```
+
+### For Development
+
+```bash
+git clone git@signorovitch.org:scl/scl --recurse-submodules && cd scl
+make all test
+./scl.out
+```
+
+If you wish to run tests, make sure to run `git clone --recurse-submodules` to
+include the [Unity](https://github.com/ThrowTheSwitch/Unity) test framework.
+*Note that tests are currently in poor use. I hope to amend this in the future.*
+
+## Syntax
+
+SCL's syntax will feel familiar to other functional programming languages.
+
+```scl
+> x = 3 + 3 * 3; x + 1
+= 13
+> f(x) x + 1
+> f(1)
+= 2
+> (\(x) 2 * x)(5)
+= 10
+> f(g) g(2)
+> f(\(x) 2 * x)
+= 4
+```
+
+Here's a simple factorial function, using recursion:
+
+```scl
+> fac(n) = {
+>   f(n, a) = {
+>     if n == 1
+>       a
+>     else
+>       f(n - 1, a * n);
+>   }
+>
+>   f(n, 1);
+> }
+```
+
+SCL's syntax is quite flexible. The above function could be more concisely
+written as:
+
+```scl
+> fac(n) (n, 1) -> f(n, a) ? n == 1 a f(n - 1, a * n)
+```

+EXCEPTION HANDLING: exception ast type should have as data a giant enum of

- * Configuration Options
- *-------------------------------------------------------
- * All options described below should be passed as a compiler flag to all files using Unity. If you must add #defines, place them BEFORE the #include above.
-
- * Integers/longs/pointers
- *     - Unity attempts to automatically discover your integer sizes
- *       - define UNITY_EXCLUDE_STDINT_H to stop attempting to look in <stdint.h>
- *       - define UNITY_EXCLUDE_LIMITS_H to stop attempting to look in <limits.h>
- *     - If you cannot use the automatic methods above, you can force Unity by using these options:
- *       - define UNITY_SUPPORT_64
- *       - set UNITY_INT_WIDTH
- *       - set UNITY_LONG_WIDTH
- *       - set UNITY_POINTER_WIDTH
-
- * Floats
- *     - define UNITY_EXCLUDE_FLOAT to disallow floating point comparisons
- *     - define UNITY_FLOAT_PRECISION to specify the precision to use when doing TEST_ASSERT_EQUAL_FLOAT
- *     - define UNITY_FLOAT_TYPE to specify doubles instead of single precision floats
- *     - define UNITY_INCLUDE_DOUBLE to allow double floating point comparisons
- *     - define UNITY_EXCLUDE_DOUBLE to disallow double floating point comparisons (default)
- *     - define UNITY_DOUBLE_PRECISION to specify the precision to use when doing TEST_ASSERT_EQUAL_DOUBLE
- *     - define UNITY_DOUBLE_TYPE to specify something other than double
- *     - define UNITY_EXCLUDE_FLOAT_PRINT to trim binary size, won't print floating point values in errors
-
- * Output
- *     - by default, Unity prints to standard out with putchar.  define UNITY_OUTPUT_CHAR(a) with a different function if desired
- *     - define UNITY_DIFFERENTIATE_FINAL_FAIL to print FAILED (vs. FAIL) at test end summary - for automated search for failure
-
- * Optimization
- *     - by default, line numbers are stored in unsigned shorts.  Define UNITY_LINE_TYPE with a different type if your files are huge
- *     - by default, test and failure counters are unsigned shorts.  Define UNITY_COUNTER_TYPE with a different type if you want to save space or have more than 65535 Tests.
-
- * Test Cases
- *     - define UNITY_SUPPORT_TEST_CASES to include the TEST_CASE macro, though really it's mostly about the runner generator script
-
- * Parameterized Tests
- *     - you'll want to create a define of TEST_CASE(...), TEST_RANGE(...) and/or TEST_MATRIX(...) which basically evaluates to nothing
-
- * Tests with Arguments
- *     - you'll want to define UNITY_USE_COMMAND_LINE_ARGS if you have the test runner passing arguments to Unity
