## Extra tests

These extra tests are intended to be run from a Vagrant VM that has already had its environment set up -- see the section in the README for more details.
Replace the testcases script with a Vagrant VM See the README section for more details. Basically, with this way, we can store a bunch of existing valid exa outputs, change a VM's environment to match our values, then check that exa still works by comparing outputs. 2016-10-07 18:31:03 +00:00			`## Extra tests`
