I'm mostly finished refactoring all the r7rs srfi-204 libraries to use srfi-206, which just leaves Chez and Loko.

I know I need to convert the define-library keywords to library keywords but I'm not sure how to handle the cond-expands.

I also just found out in the process of moving test/ out of the srfi/ directory that loko's include seems to work like guile's load - whether it works or not depends on what directory you're in when you import the library (as opposed to the others which all work relative to the file they are in).
