#### Compiler for the Pyramid Scheme esolang

[Pyramid Scheme](<https://github.com/ConorOBrien-Foxx/Pyramid-Scheme>) is an esoteric language whose programs are ascii-art pyramids. psll lets you write them in a lisp-like syntax instead, with macros, strings, `def` and code-golf optimisations, and compiles that to the pyramids for you.

For example, this psll program

```
 (set a 6) (set b 7)
 (out (* a b))
```

compiles to

```
     ^        ^          ^
    / \      / \        / \
   /set\    /set\      /out\
  ^-----^  ^-----^    ^-----
 /a\   /6\/b\   /7\  /*\
 ---   ------   --- ^---^
                   /a\ /b\
                   --- ---
```

and prints `42`.

Commands:

* `psll compile prog.psll -o prog.pyra` -- compile to Pyramid Scheme
* `psll run prog.pyra` -- run a Pyramid Scheme program
* `psll compile-and-run prog.psll` -- both in one go

Ruby and the Pyramid Scheme interpreter are bundled, so everything works offline out of the box.
