How to make graphs for tikz easily

Necessary utilities: graphviz, dot2tex, xsel. Install these:

$ sudo apt install graphviz
$ sudo apt install xsel
$ pip3 install dot2tex

import sys
import PyPDF4
import re

## Usage: arxiref.py 1711.07059 
##    or: arxiref.py paper.pdf
## If given something that looks like an arXiv id, searches for something with that name
## If given a filename, treats it as a pdf, looks for an arXiv id on page 1, then proceeds as in first case

So, haskell is a "Pure Functional" language, which basically means that functions behave(almost) like mathematical functions, rather than how they behave in other languages. So in most other languages a function can do whatever before it returns, print some text, wipe the root partition, launch nukes against China, whatever. In haskell, that's (almost) not allowed: a function takes an argument, returns an argument, and that's it.

So how do you accomplish anything? Software has to actually do stuff, so how do you interact with anything? To explain that, we need a brief interlude to explain types in haskell. First there are simple types like int, string, so on. Just like a type in C. Then you have parametric types, like List. So you can have a List int, or a List string, and that's a linked list of integers or strings. Lastly, we need to explain parametric types. For example, you might have a function that takes the length of a list. The thing about that function is that it actually doesn't care abou
