29The editor 'ee' (easy editor) is intended to be a simple, easy to use 
30terminal-based screen oriented editor that requires no instruction to 
31use.  Its primary use would be for people who are new to computers, or who 
32use computers only for things like e-mail.
33
34ee's simplified interface is highlighted by the use of pop-up menus which 
35make it possible for users to carry out tasks without the need to 
36remember commands.  An information window at the top of the screen shows 
37the user the operations available with control-keys.
38
39ee allows users to use full eight-bit characters.  If the host system has 
40the capabilities, ee can use message catalogs, which would allow users to 
41translate the message catalog into other languages which use eight-bit 
42characters.  See the file ee.i18n.guide for more details.
43
44ee relies on the virtual memory abilities of the platform it is running on 
45and does not have its own memory management capabilities.
46
47I am releasing ee because I hate to see new users and non-computer types 
48get frustrated by vi, and would like to see more intuitive interfaces for 
49basic tools (both character-based and graphical) become more pervasive.
50Terminal capabilities and communication speeds have evolved considerably 
51since the time in which vi's interface was created, allowing much more 
52intuitive interfaces to be used.  Since character-based I/O won't be 
53completely replaced by graphical user interfaces for at least a few more 
54years, I'd like to do what I can to make using computers with less 
55glamorous interfaces as easy to use as possible.  If terminal interfaces 
56are still used in ten years, I hope neophytes won't still be stuck with 
57only vi.
58
59For a text editor to be easy to use requires a certain set of abilities.  In 
60order for ee to work, a terminal must have the ability to position the cursor 
61on the screen, and should have arrow keys that send unique sequences 
62(multiple characters, the first character is an "escape", octal code 
63'\033').  All of this information needs to be in a database called "terminfo" 
64(System V implementations) or "termcap" (usually used for BSD systems).  In 
65case the arrow keys do not transmit unique sequences, motion operations are 
66mapped to control keys as well, but this at least partially defeats the 
67purpose.  The curses package is used to handle the I/O which deals with the 
68terminal's capabilities.  
69
70While ee is based on curses, I have included here the source code to 
71new_curse, a subset of curses developed for use with ee.  'curses' often  
72will have a defect that reduces the usefulness of the editor relying upon 
73it.  
74
75The file new_curse.c contains a subset of 'curses', a package for 
76applications to use to handle screen output.  Unfortunately, curses 
77varies from system to system, so I developed new_curse to provide 
78consistent behavior across systems.  It works on both SystemV and BSD 
79systems, and while it can sometimes be slower than other curses packages, 
80it will get the information on the screen painted correctly more often 
81than vendor supplied curses.  Unless problems occur during the building 
82of ee, it is recommended that you use new_curse rather than the curses 
83supplied with your system.
84
85If you experience problems with data being displayed improperly, check 
86your terminal configuration, especially if you're using a terminal 
87emulator, and make sure that you are using the right terminfo entry 
88before rummaging through code.  Terminfo entries often contain 
89inaccuracies, or incomplete information, or may not totally match the 
90terminal or emulator the terminal information is being used with.  
91Complaints that ee isn't working quite right often end up being something 
92else (like the terminal emulator being used).  
93
94Both ee and new_curse were developed using K&R C (also known as "classic 
95C"), but it can also be compiled with ANSI C.  You should be able to 
96build ee by simply typing "make".  A make file which takes into account 
97the characteristics of your system will be created, and then ee will be 
98built.  If there are problems encountered, you will be notified about 
99them.

101ee is the result of several conflicting design goals.  While I know that it 
102solves the problems of some users, I also have no doubt that some will decry 
103its lack of more features.  I will settle for knowing that ee does fulfill 
104the needs of a minority (but still large number) of users.  The goals of ee 
105are: 
106
107        1. To be so easy to use as to require no instruction.
108        2. To be easy to compile and, if necessary, port to new platforms 
109           by people with relatively little knowledge of C and UNIX.
110        3. To have a minimum number of files to be dealt with, for compile 
111           and installation.
112        4. To have enough functionality to be useful to a large number of 
113           people.
