This is the Vim editor license. README.txt for version 6.1 of Vim: Vi IMproved. WHAT IS VIM Vim is an almost compatible version of the UNIX editor Vi. Many new features have been added: multi-level undo, syntax highlighting, command line history, on-line help, filename completion, block operations, etc. There is also a Graphical User Interface (GUI) available. See "runtime/doc/vi_diff.txt" for differences with Vi. This editor is very useful for editing programs and other plain ASCII files. All commands are given with normal keyboard characters, so those who can type with ten fingers can work very fast. Additionally, function keys can be defined by the user, and the mouse can be used. Vim currently runs under Amiga DOS, MS-DOS, MS-Windows 95/98/NT, Atari MiNT, Macintosh, BeOS, VMS, RISC OS, OS/2 and almost all flavours of UNIX. Porting to other systems should not be very difficult. DISTRIBUTION There are separate distributions for Unix, PC, Amiga and some other systems. This README.txt file comes with the runtime archive. It includes the documentation, syntax files and other files that are used at runtime. To run Vim you must get either one of the binary archives or a source archive. Which one you need depends on the system you want to run it on and whether you want or must compile it yourself. Check "http://vim.sf.net/download.php" for an overview of currently available distributions. DOCUMENTATION The best is to use ":help" in Vim. If you don't have an executable yet, read "runtime/doc/help.txt". It contains pointers to the other documentation files. The User Manual reads like a book and is recommended to learn to use Vim. See ":help user-manual". The vim tutor is a one hour training course for beginners. Mostly it can be started as "vimtutor". See ":help tutor" for more information. COPYING Vim is Charityware. You can use and copy it as much as you like, but you are encouraged to make a donation to orphans in Uganda. Please read the file "runtime/doc/uganda.txt" for details. There are no restrictions on distributing an unmodified copy of Vim. Parts of Vim may also be distributed, but this text must always be included. You are allowed to include executables that you made from the unmodified Vim sources, your own usage examples and Vim scripts. If you distribute a modified version of Vim, you are encouraged to send the maintainer a copy, including the source code. Or make it available to the maintainer through ftp; let him know where it can be found. If the number of changes is small (e.g., a modified Makefile) e-mailing the diffs will do. When the maintainer asks for it (in any way) you must make your changes, including source code, available to him. The maintainer reserves the right to include any changes in the official version of Vim. This is negotiable. You are not allowed to distribute a modified version of Vim when you are not willing to make the source code available to the maintainer. The current maintainer is Bram Moolenaar . If this changes, it will be announced in appropriate places (most likely www.vim.org and comp.editors). When it is completely impossible to contact the maintainer, the obligation to send him modified source code ceases. It is not allowed to remove these restrictions from the distribution of the Vim sources or parts of it. These restrictions may also be used for previous Vim releases instead of the text that was included with it.
