System.Ext2
Description
This library exists for me to learn about ext2 and to possibly be used as part of an assignment in a Computer Science course I will be taking soon.
Please feel free to use it to learn about ext2 and play around, but don't use it for anything that you care about for now, because I don't trust myself.
