This is done by the ``write-you-a-haskell.cabal`` and ``stack.yaml`` files. **Stack** ```bash $ stack exec make ``` To generate the pdf, the LaTeX packages must be installed on the system. ```bash $ sudo apt-get install texlive-xetex texlive-latex-extra $ sudo apt-get install xzdec $ sudo tlmgr install zapfding $ stack exec make pdf ``` Generation of the epub is also supported. ```bash $ stack exec make epub ``` **Cabal** ```bash $ cabal sandbox init $ cabal install --only-dependencies $ cabal exec bash $ make ``` Contributing ------------ Any and all contributions are always welcome. As always, I rely on the perpetual kindness and goodwill of Haskellers (like you!) to help correct grammar, clarify, and fix errors. * [Contributing](http://dev.stephendiehl.com/fun/contributing.html) License ------- This written work is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License.
