3.2 Prerequisites

This document is very far from self-contained. It assumes the following:

• The reader knows the C programming language at least well enough to understand function prototypes and return values.
• The reader has read the documents for one of Libmarpa’s upper layers. As of this writing, the only such layer is Marpa::R2 or Marpa::R3, in Perl.
• The reader knows some parsing theory. See Parsing theory preliminaries.
