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). Using Racket 6.0+, install from the command line like so: raco pkg install pollen And update like so: raco pkg update pollen Docs are installed with the package. You can also [read the docs here](http://pkg-build.racket-lang.org/doc/pollen).
