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 'd8' by default, but :CrBuild target1 target2 etc works as well,
12" i.e. :CrBuild all or :CrBuild d8 cctest unittests.
13"
14" Requires that gyp has already generated build.ninja files, and that ninja is
15" in your path (which it is automatically if depot_tools is in your path).
16" Bumps the number of parallel jobs in ninja automatically if goma is
17" detected.
18"
19" Add the following to your .vimrc file:
20"     so /path/to/src/tools/vim/ninja-build.vim
