38 | This editor was purposely developed to be simple, both in
39 | interface and implementation. This editor was developed to
40 | address a specific audience: the user who is new to computers
41 | (especially UNIX).
42 |
43 | ee is not aimed at technical users; for that reason more
44 | complex features were intentionally left out. In addition,
45 | ee is intended to be compiled by people with little computer
46 | experience, which means that it needs to be small, relatively
47 | simple in implementation, and portable.
