+# Miscellaneous auto-load Vim scripts
+
+The git repository at <http://github.com/xolox/vim-misc> contains Vim scripts
+that are used by most of the [Vim plug-ins I've written] [plugins] yet don't
+really belong with any single one. I'm hoping to include this repository as a
+git submodule in my other repositories so that I only have to maintain these
+files in one place.
+
+For lack of a better place: I hereby release these scripts under the MIT
+license, in other words feel free to do with them as you please but don't
+misrepresent this work as your own.
+
+[plugins]: http://peterodding.com/code/vim/
