+# This file is a minimal clang-format sublime-integration. To install:
+# - Change 'binary' if clang-format is not on the path (see below).
+# - Put this file into your sublime Packages directory, e.g. on Linux:
+#     ~/.config/sublime-text-2/Packages/User/clang-format-sublime.py
+# - Add a key binding:
+#     { "keys": ["ctrl+shift+c"], "command": "clang_format" },
+#
+# With this integration you can press the bound key and clang-format will
+# format the current lines and selections for all cursor positions. The lines
+# or regions are extended to the next bigger syntactic entities.
+#
+# It operates on the current, potentially unsaved buffer and does not create
+# or save any files. To revert a formatting, just undo.
