//! This program is mainly intended for generating the dumps that are compiled in to
//! syntect, not as a helpful example for beginners.
//! Although it is a valid example for serializing syntaxes, you probably won't need
//! to do this yourself unless you want to cache your own compiled grammars.
//!
//! An example of how this script is used to generate the pack files included
//! with syntect can be found under `make packs` in the Makefile.
