 # "All" is an alias for "gn_all". It exists for bot compatibility w/ GYP for
 # the iOS bots and the official builders, but should not be generally used

 # same set of targets as GYP's "All" does, because GYP's "All" supports
 # wildcards.

 # Lastly, none of these targets are guaranteed to be the same as what ninja
 # will build with "all". For more on how "all" works and the differences in how
 # GYP and GN determine "all", see crbug.com/503241.
