This repo is a collection of documents about Linguistics Olympiad written by me.
Most in Chinese I guess.
As you can see this is rather a collections of small projects. You may be more interested in only one or two directories. Since check out partial repo is impossible in Git, you need SVN:
svn export https://github.com/notcome/About-Linguistics-Olympiad/trunk/interesting-directory
Though most people are only interested in the result PDF, you may need to modify and therefore recompile everything.
I use Computer Modern Unicode for IPA.
Other fonts. Well, with a modern OS X (Mavericks for IOL 2014 Analysis for example), I guess everything would be OK. Ohterwise, rechoose fonts wouldn't be hard either, for all definitions are put at the head of main file.
