## Pollen: the book is a program

A book-publishing system written in [Racket](http://racket-lang.org). Unstable. Incomplete. Et cetera. It’s becoming more civilized. But this is the actual software I use to publish & maintain my web-based book [Butterick’s Practical Typography](http://practicaltypography.com).

If you think documents should be programmable, you’ll love it.  
If not, you can move along.

Pollen gives you access to a full programming language (Racket) with a text-based syntax that makes it easy to embed code within your documents.
