 # Instantiate grit. This will produce a script target to run grit, and a
 # static library that compiles the .cc files.
 #
 # Parameters
 #
 #   source
 #       Path to .grd file.
 #
 #   grit_flags (optional)
 #       List of strings containing extra command-line flags to pass to Grit.
 #
 #   deps  (optional)
 #   visibility  (optional)
 #       Normal meaning.
 #
 # Example
 #
 #   grit("my_resources") {
 #     source = "myfile.grd"  # source is required.
 #     grit_flags = [ "-E", "foo=bar" ]  # Optional extra flags.
 #     # You can also put deps here if the grit source depends on generated
 #     # files.

This logic is odd given that enable_printing sounds like a boolean.  Do you know
the domain of values for enable_printing? Can we explain why "== 1" translates
to "enable_full_printing"?

Yeah, I've been wanting to rename it. Currently it matches the GYP exactly.
Another case like this I renamed to foo_mode. I still plan to get to it, but I
will have to update all the files that reference it so it's not super trivial.

The reason that =1 means "full" is that it used to be 0/1 like everything else,
and then the Android people came by and hacked on a partial mode and 0 and 1
were taken, so they used 2. Yes, this is very sad.

I almost want the ability to take an array of strings, check for the
corresponding boolean, and then add them into another array. Sounds too
complicated for the GN language though. :-/
