VIM LICENSE
I) There are no restrictions on distributing unmodified copies of
pathogen.vim except that they must include this license text. You can
also distribute unmodified parts of pathogen.vim, likewise unrestricted
except that they must include this license text. You are also allowed to
include executables that you made from the unmodified pathogen.vim
sources, plus your own usage examples and Vim scripts.
II) It is allowed to distribute a modified (or extended) version of
pathogen.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 pathogen.vim must be distributed in one of the following
five ways:
a) If you make changes to pathogen.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
pathogen.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 pathogen.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 pathogen.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 pathogen.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
pathogen.vim.
d) When you have a modified pathogen.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 pathogen.vim without fee or restriction.
- You keep the changes for at least three years after last
distributing the corresponding modified pathogen.vim. When the
maintainer or someone who you distributed the modified
pathogen.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 pathogen.vim,
or as long as possible.
e) When the GNU General Public License (GPL) applies to the changes,
you can distribute the modified pathogen.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
pathogen.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 pathogen.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
pathogen.vim sources, parts of it or from a modified version. You may
use this license for previous pathogen.vim releases instead of the
license that they came with, at your option.
