 -- In this file, change "/path/to/" to the path where you installed clang-format
 -- and save it to ~/Library/Application Support/BBEdit/Scripts. You can then
 -- select the script from the Script menu and clang-format will format the
 -- selection. Note that you can rename the menu item by renaming the script, and
 -- can assign the menu item a keyboard shortcut in the BBEdit preferences, under
 -- Menus & Shortcuts.
