37 | This editor was purposely developed to be simple, both in

41 |
42 | ee is not aimed at technical users; for that reason more
43 | complex features were intentionally left out. In addition,
44 | ee is intended to be compiled by people with little computer
45 | experience, which means that it needs to be small, relatively
46 | simple in implementation, and portable.
