      5 " Adds a "Compile this file" function, using ninja. On Mac, binds Cmd-k to
      6 " this command. On Windows, Ctrl-F7 (which is the same as the VS default).
      7 " On Linux, <Leader>o, which is \o by default ("o"=creates .o files)
      8 "
      9 " Adds a "Build this target" function, using ninja. This is not bound
     10 " to any key by default, but can be used via the :CrBuild command.
     11 " It builds 'chrome' by default, but :CrBuild target1 target2 etc works as well.
     12 "
     13 " Requires that gyp has already generated build.ninja files, and that ninja is
     14 " in your path (which it is automatically if depot_tools is in your path).
