This document describes the grammar for the textual form of the Vortex compiler's RTL intermediate language. This is the language used to communicate between the C++, Modula-3, and Java front-ends and Vortex, and is also used to describe some Cecil primitives. These grammar rules are considered to extend those in the Cecil language reference manual.

Warning: the RTL language was not designed from scratch, but rather evolved via accretion of features. It is slowly being reworked to make the operators more general and language-independent, but this process is not complete.
