Hello Guix,

This makes our tesseract-ocr package usable.  Here's a small experiment
comparing GNU Ocrad vs Tesseract on a LightDM login screendump from QEMU:

--8<---------------cut here---------------start------------->8---
$ time ocrad -i -s 10 /tmp/dump.ppm
komput�lo _ O Tht_, _l_.__ �

real    0m9.616s
user    0m9.397s
sys     0m0.157s

$ time tesseract -l eng /tmp/dump.ppm out && cat out.txt
Estimating resolution as 133

real    0m0.389s
user    0m0.602s
sys     0m0.053s
komputilo QR @ Thu, 21:32 ©

--8<---------------cut here---------------end--------------->8---

Maxim Cournoyer (2):
  gnu: Add tesseract-ocr-tessdata-fast.
  gnu: tesseract-ocr: Make the default install minimally useful.
