+			 The "Artistic License"
+
+				Preamble
+
+The intent of this document is to state the conditions under which a
+Package may be copied, such that the Copyright Holder maintains some
+semblance of artistic control over the development of the package,
+while giving the users of the package the right to use and distribute
+the Package in a more-or-less customary fashion, plus the right to make
+reasonable modifications.
+
+Definitions:
+
+	"Package" refers to the collection of files distributed by the
+	Copyright Holder, and derivatives of that collection of files
+	created through textual modification.
+
+	"Standard Version" refers to such a Package if it has not been
+	modified, or has been modified in accordance with the wishes
+	of the Copyright Holder.
+
+	"Copyright Holder" is whoever is named in the copyright or
+	copyrights for the package.
+
+	"You" is you, if you're thinking about copying or distributing
+	this Package.
+
+	"Reasonable copying fee" is whatever you can justify on the
+	basis of media cost, duplication charges, time of people involved,
+	and so on.  (You will not be required to justify it to the
+	Copyright Holder, but only to the computing community at large
+	as a market that must bear the fee.)
+
+	"Freely Available" means that no fee is charged for the item
+	itself, though there may be fees involved in handling the item.
+	It also means that recipients of the item may redistribute it
+	under the same conditions they received it.
+
+1. You may make and give away verbatim copies of the source form of the
+Standard Version of this Package without restriction, provided that you
+duplicate all of the original copyright notices and associated disclaimers.
+
+2. You may apply bug fixes, portability fixes and other modifications
+derived from the Public Domain or from the Copyright Holder.  A Package
+modified in such a way shall still be considered the Standard Version.
+
+3. You may otherwise modify your copy of this Package in any way, provided
+that you insert a prominent notice in each changed file stating how and
+when you changed that file, and provided that you do at least ONE of the
+following:
+
+    a) place your modifications in the Public Domain or otherwise make them
+    Freely Available, such as by posting said modifications to Usenet or
+    an equivalent medium, or placing the modifications on a major archive
+    site such as uunet.uu.net, or by allowing the Copyright Holder to include
+    your modifications in the Standard Version of the Package.
+
+    b) use the modified Package only within your corporation or organization.
+
+    c) rename any non-standard executables so the names do not conflict
+    with standard executables, which must also be provided, and provide
+    a separate manual page for each non-standard executable that clearly
+    documents how it differs from the Standard Version.
+
+    d) make other distribution arrangements with the Copyright Holder.
+
+4. You may distribute the programs of this Package in object code or
+executable form, provided that you do at least ONE of the following:
+
+    a) distribute a Standard Version of the executables and library files,
+    together with instructions (in the manual page or equivalent) on where
+    to get the Standard Version.
+
+    b) accompany the distribution with the machine-readable source of
+    the Package with your modifications.
+
+    c) accompany any non-standard executables with their corresponding
+    Standard Version executables, giving the non-standard executables
+    non-standard names, and clearly documenting the differences in manual
+    pages (or equivalent), together with instructions on where to get
+    the Standard Version.
+
+    d) make other distribution arrangements with the Copyright Holder.
+
+5. You may charge a reasonable copying fee for any distribution of this
+Package.  You may charge any fee you choose for support of this Package.
+You may not charge a fee for this Package itself.  However,
+you may distribute this Package in aggregate with other (possibly
+commercial) programs as part of a larger (possibly commercial) software
+distribution provided that you do not advertise this Package as a
+product of your own.
+
+6. The scripts and library files supplied as input to or produced as
+output from the programs of this Package do not automatically fall
+under the copyright of this Package, but belong to whomever generated
+them, and may be sold commercially, and may be aggregated with this
+Package.
+
+7. C subroutines supplied by you and linked into this Package in order
+to emulate subroutines and variables of the language defined by this
+Package shall not be considered part of this Package, but are the
+equivalent of input as in Paragraph 6, provided these subroutines do
+not change the language in any way that would cause it to fail the
+regression tests for the language.
+
+8. The name of the Copyright Holder may not be used to endorse or promote
+products derived from this software without specific prior written permission.
+
+9. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR
+IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED
+WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE.

+
+
+The editor 'ee' (easy editor) is intended to be a simple, easy to use 
+terminal-based screen oriented editor that requires no instruction to 
+use.  Its primary use would be for people who are new to computers, or who 
+use computers only for things like e-mail.
+
+ee's simplified interface is highlighted by the use of pop-up menus which 
+make it possible for users to carry out tasks without the need to 
+remember commands.  An information window at the top of the screen shows 
+the user the operations available with control-keys.
+
+ee allows users to use full eight-bit characters.  If the host system has 
+the capabilities, ee can use message catalogs, which would allow users to 
+translate the message catalog into other languages which use eight-bit 
+characters.  See the file ee.i18n.guide for more details.
+
+ee relies on the virtual memory abilities of the platform it is running on 
+and does not have its own memory management capabilities.
+
+I am releasing ee because I hate to see new users and non-computer types 
+get frustrated by vi, and would like to see more intuitive interfaces for 
+basic tools (both character-based and graphical) become more pervasive.
+Terminal capabilities and communication speeds have evolved considerably 
+since the time in which vi's interface was created, allowing much more 
+intuitive interfaces to be used.  Since character-based I/O won't be 
+completely replaced by graphical user interfaces for at least a few more 
+years, I'd like to do what I can to make using computers with less 
+glamorous interfaces as easy to use as possible.  If terminal interfaces 
+are still used in ten years, I hope neophytes won't still be stuck with 
+only vi.  
+
+For a text editor to be easy to use requires a certain set of abilities.  In 
+order for ee to work, a terminal must have the ability to position the cursor 
+on the screen, and should have arrow keys that send unique sequences 
+(multiple characters, the first character is an "escape", octal code 
+'\033').  All of this information needs to be in a database called "terminfo" 
+(System V implementations) or "termcap" (usually used for BSD systems).  In 
+case the arrow keys do not transmit unique sequences, motion operations are 
+mapped to control keys as well, but this at least partially defeats the 
+purpose.  The curses package is used to handle the I/O which deals with the 
+terminal's capabilities.  
+
+While ee is based on curses, I have included here the source code to 
+new_curse, a subset of curses developed for use with ee.  'curses' often  
+will have a defect that reduces the usefulness of the editor relying upon 
+it.  
+
+The file new_curse.c contains a subset of 'curses', a package for 
+applications to use to handle screen output.  Unfortunately, curses 
+varies from system to system, so I developed new_curse to provide 
+consistent behavior across systems.  It works on both SystemV and BSD 
+systems, and while it can sometimes be slower than other curses packages, 
+it will get the information on the screen painted correctly more often 
+than vendor supplied curses.  Unless problems occur during the building 
+of ee, it is recommended that you use new_curse rather than the curses 
+supplied with your system.
+
+If you experience problems with data being displayed improperly, check 
+your terminal configuration, especially if you're using a terminal 
+emulator, and make sure that you are using the right terminfo entry 
+before rummaging through code.  Terminfo entries often contain 
+inaccuracies, or incomplete information, or may not totally match the 
+terminal or emulator the terminal information is being used with.  
+Complaints that ee isn't working quite right often end up being something 
+else (like the terminal emulator being used).  
+
+Both ee and new_curse were developed using K&R C (also known as "classic 
+C"), but it can also be compiled with ANSI C.  You should be able to 
+build ee by simply typing "make".  A make file which takes into account 
+the characteristics of your system will be created, and then ee will be 
+built.  If there are problems encountered, you will be notified about 
+them. 
+
+ee is the result of several conflicting design goals.  While I know that it 
+solves the problems of some users, I also have no doubt that some will decry 
+its lack of more features.  I will settle for knowing that ee does fulfill 
+the needs of a minority (but still large number) of users.  The goals of ee 
+are: 
+
+        1. To be so easy to use as to require no instruction.
+        2. To be easy to compile and, if necessary, port to new platforms 
+           by people with relatively little knowledge of C and UNIX.
+        3. To have a minimum number of files to be dealt with, for compile 
+           and installation.
+        4. To have enough functionality to be useful to a large number of 
+           people.

+Easy Editor ("ee") provides the ability to translate the messages displayed to 
+the user and the commands entered.  This is done via message catalogs, 
+following X/Open standards.  ee only supports eight bit characters.
+
+(The name ee.i18n.guide is for "ee internationalization guide".  The i18n 
+abbreviation is used because there are 18 characters between the first 
+letter ("i") and last ("n") of "internationalization".)
+
+All of the messages, warnings, information, and commands, are contained in the 
+message catalog.  Each numbered entry represents an individual string used by 
+ee.  Some strings contain formatting information for formatted print 
+statements, which are of the form "%s", or "%d", these must be preserved in 
+the translation, or the correct information will not be displayed.  For those 
+strings containing multiple formatting codes, the order of each item must be 
+preserved as well.
+
+Message		content 
+1 		title for modes, or settings menu
+2 - 8		entries for modes menu, each line should be the same length 
+		 (padded with spaces)
+9 - 34		other menu titles and entries

+57 - 61 	actions assigned to control keys 
+62 - 66 	commands information

+74		string used to display the decimal value of the character 
+		 the cursor is on 
+75		string displaying an unrecognized command 
+76 		string indicating that the command entered is not a unique 
+		 substring of a valid command
+77		string indicating the current line number 
+78		string for displaying the length of the line 
+79		string for displaying the name of the file 
+80 - 83		strings showing how to invoke ee, and its options
+84		message indicating that the file entered is a directory, not a 
+		 text file
+85		message informing that the entered file does not yet exist

+		 entered for a file to edit)

+		 (can be upper or lower case, will be converted to upper-case 
+		 during test)

+		 allow the user to exit the menu
+106		error message indicating the menu won't fit on the screen
+107		self-explanatory
+108		prompt for shell command
+109		message displayed while formatting a paragraph
+110		string which places message for spell checking at top of 
+		 buffer (the portions 'list of unrecognized words' and 
+		 '-=-=-=-=-=-' may be replaced, but the rest must remain the 
+		 same)
+111		message informing that spell checking is in progress
+112		prompt for right margin
+113		error informing user that operation is not permitted in ree
+114		string indicating mode is turned 'on' in modes menu
+115		string indicating mode is turned 'off' in modes menu

+132 - 144	strings used for initialization
+145		entry for settings menu for emacs key bindings settings
+146 - 153	help screen entries for emacs key bindings info
+154 - 158	info window entries for emacs key bindings info
+159		string for turning on emacs key bindings in the init file
+160		string for turning off emacs key bindings in the init file
+
+Care should be taken when translating commands and initialization keywords 
+because the algorithm used for detecting uniqueness of entered commands 
+will not be able to distinguish words that are not unique before the end 
+of the shorter word, for example, it would not be able to distinguish the 
+command 'abcd' from 'abcde'.
+
+After translating the messages, use the 'gencat' command to create the compiled 
+catalog used when running the software.  The standard syntax would be:
+
+	gencat ee.cat ee.msg
+
+Where ee.msg is the file containing the translations, and ee.cat is the 
+compiled catalog.  If the file ee.cat does not exist, it will be created.  
+Check the documentation for your system for proper syntax.  
+
+Message catalog placement varies from system to system.  A common location 
+for message catalogs is in /usr/lib/nls.  In this directory are 
+directories with the names of other languages.  The default language is 
+'C'.  There is also an environment variable, named NLSPATH used to 
+determine where message catalogs can be found.  This variable is similar 
+to the PATH variable used for commands, but with some differences.  The 
+NLSPATH variable must have the ability to handle different names for 
+languages and the catalog files, so it has field descriptors for these.  A 
+typical setting for NLSPATH could be:
+
+	NLSPATH=/usr/lib/nls/%L/%N.cat:/usr/local/lib/nls/%L/%N.cat
+
+Where "%L" is the field descriptor for the language (obtained from the 
+LANG environment variable) and "%N" is the name of the file (with the 
+".cat" appended by the path variable, it is not passed from the requesting 
+program).  The colon (:) is used to separate paths, so in the above 
+example there are two paths possible for message catalogs.  You may wish 
+to maintain catalogs for applications that are not supported by your 
+system vendor in a location unique for you, and this is facilitated by the 
+NLSPATH variable.  Remember to set and export both the LANG and NLSPATH 
+variables for each user that expects to use localization either in a 
+system-wide profile or in each user's profile.  See your system 
+documentation for more information.
+
+The message catalog supplied with ee also uses the '$quote' directive to 
+specify a quote around strings to ensure proper padding.  This directive 
+may not be supported on all systems, and lead to quotes being included in 
+the string used in ee, which will cause incorrect behavior.  If the 
+'$quote' directive is not supported by your system's gencat command, edit 
+the msg file to remove the leading and trailing quotation marks.
