+VIM LICENSE
+
+I) There are no restrictions on distributing unmodified copies of Vim except
+ that they must include this license text. You can also distribute
+ unmodified parts of Vim, likewise unrestricted except that they must
+ include this license text. You are also allowed to include executables
+ that you made from the unmodified Vim sources, plus your own usage
+ examples and Vim scripts.
+
+II) It is allowed to distribute a modified (or extended) version of Vim,
+ including executables and/or source code, when the following four
+ conditions are met:
+ 1) This license text must be included unmodified.
+ 2) The modified Vim must be distributed in one of the following five ways:
+ a) If you make changes to Vim yourself, you must clearly describe in
+ the distribution how to contact you. When the maintainer asks you
+ (in any way) for a copy of the modified Vim you distributed, you
+ must make your changes, including source code, available to the
+ maintainer without fee. The maintainer reserves the right to
+ include your changes in the official version of Vim. What the
+ maintainer will do with your changes and under what license they
+ will be distributed is negotiable. If there has been no negotiation
+ then this license, or a later version, also applies to your changes.
+ The current maintainer is Bram Moolenaar <Bram@vim.org>. If this
+ changes it will be announced in appropriate places (most likely
+ vim.sf.net, www.vim.org and/or comp.editors). When it is completely
+ impossible to contact the maintainer, the obligation to send him
+ your changes ceases. Once the maintainer has confirmed that he has
+ received your changes they will not have to be sent again.
+ b) If you have received a modified Vim that was distributed as
+ mentioned under a) you are allowed to further distribute it
+ unmodified, as mentioned at I). If you make additional changes the
+ text under a) applies to those changes.
+ c) Provide all the changes, including source code, with every copy of
+ the modified Vim you distribute. This may be done in the form of a
+ context diff. You can choose what license to use for new code you
+ add. The changes and their license must not restrict others from
+ making their own changes to the official version of Vim.
+ d) When you have a modified Vim which includes changes as mentioned
+ under c), you can distribute it without the source code for the
+ changes if the following three conditions are met:
+ - The license that applies to the changes permits you to distribute
+ the changes to the Vim maintainer without fee or restriction, and
+ permits the Vim maintainer to include the changes in the official
+ version of Vim without fee or restriction.
+ - You keep the changes for at least three years after last
+ distributing the corresponding modified Vim. When the maintainer
+ or someone who you distributed the modified Vim to asks you (in
+ any way) for the changes within this period, you must make them
+ available to him.
+ - You clearly describe in the distribution how to contact you. This
+ contact information must remain valid for at least three years
+ after last distributing the corresponding modified Vim, or as long
+ as possible.
+ e) When the GNU General Public License (GPL) applies to the changes,
+ you can distribute the modified Vim under the GNU GPL version 2 or
+ any later version.
+ 3) A message must be added, at least in the output of the ":version"
+ command and in the intro screen, such that the user of the modified Vim
+ is able to see that it was modified. When distributing as mentioned
+ under 2)e) adding the message is only required for as far as this does
+ not conflict with the license used for the changes.
+ 4) The contact information as required under 2)a) and 2)d) must not be
+ removed or changed, except that the person himself can make
+ corrections.
+
+III) If you distribute a modified version of Vim, you are encouraged to use
+ the Vim license for your changes and make them available to the
+ maintainer, including the source code. The preferred way to do this is
+ by e-mail or by uploading the files to a server and e-mailing the URL.
+ If the number of changes is small (e.g., a modified Makefile) e-mailing a
+ context diff will do. The e-mail address to be used is
+ <maintainer@vim.org>
+
+IV) It is not allowed to remove this license from the distribution of the Vim
+ sources, parts of it or from a modified version. You may use this
+ license for previous Vim releases instead of the license that they came
+ with, at your option.
