 The script generates the templates when importing.
 
 Then when `mx build` builds TruffleRuby and the `prism` mx project inside, it runs `make`.

 # Compiling Prism's AST
 
-One important class of consumers of Prism's AST is compilers. Currently [CRuby](https://github.com/ruby/ruby), [JRuby](https://github.com/jruby/jruby), [TruffleRuby](https://github.com/oracle/truffleruby), and [Natalie](https://github.com/natalie-lang/natalie) have all built compilation code on top of Prism's AST.

 This document will describe, at a high level, how CRuby's compilation of Prism's AST works.
