+" Adds a "Compile this file" function, using ninja. On Mac, binds Cmd-k to
+" this command. On Windows, Ctrl-F7 (which is the same as the VS default).
+" On Linux, <Leader>o, which is \o by default ("o"=creates .o files)
+"
+" Adds a "Build this target" function, using ninja. This is not bound
+" to any key by default, but can be used via the :CrBuild command.
+" It builds 'd8' by default, but :CrBuild target1 target2 etc works as well,
+" i.e. :CrBuild all or :CrBuild d8 cctest unittests.
+"
+" Requires that gyp has already generated build.ninja files, and that ninja is
+" in your path (which it is automatically if depot_tools is in your path).
+" Bumps the number of parallel jobs in ninja automatically if goma is
+" detected.
+"
+" Add the following to your .vimrc file:
