# =====

# for macbooks aka best books, you need to know your macbook DPI to begin with
# and it can be found on some sites like http://dpi.lv/

# you can install wkhtmltopdf on mac with something like
# `brew install caskroom/cask/wkhtmltopdf`

# afterwards, you need to rename the /usr/local/bin/wkhtmltopdf into another
# name like `wkhtmltopdf_orig` or something. then you need to write a new Bash
# script with the name `wkhtmltopdf` to call `wkhtmltopdf_orig` with the
# argument `--dpi` and the original DPI value of your best book.

#!/bin/bash
/usr/local/bin/wkhtmltopdf_orig --dpi 227 $*
