+# This file is a minimal clang-format vim-integration. To install:
+# - Change 'binary' if clang-format is not on the path (see below).
+# - Add to your .vimrc:
+#
+#   map <C-I> :pyf <path-to-this-file>/clang-format.py<cr>
+#   imap <C-I> <c-o>:pyf <path-to-this-file>/clang-format.py<cr>
+#
+# The first line enables clang-format for NORMAL and VISUAL mode, the second
+# line adds support for INSERT mode. Change "C-I" to another binding if you
+# need clang-format on a different key (C-I stands for Ctrl+i).
+#
+# With this integration you can press the bound key and clang-format will
+# format the current line in NORMAL and INSERT mode or the selected region in
+# VISUAL mode. The line or region is extended to the next bigger syntactic
+# entity.
+#
+# You can also pass in the variable "l:lines" to choose the range for
+# formatting. This variable can either contain "<start line>:<end line>" or
+# "all" to format the full file. So, to format the full file, write a function
+# like:
+# :function FormatFile()
+# :  let l:lines="all"
+# :  pyf <path-to-this-file>/clang-format.py
+# :endfunction
+#
+# It operates on the current, potentially unsaved buffer and does not create
+# or save any files. To revert a formatting, just undo.
