1"""
2SkOpts is built differently than the rest of our source files. See //src/core/SkOpts.h for
3a bit more background about what SkOpts is for and how it works.
4
5Instead of bubbling all the headers and sources up to the top level where they are compiled in
6one large library, we only bubble up the headers, so the default implementations in those files
7can be built against the minimum version of Skia (which the whole library is compiled with).
8
9We create several libraries that contain a single source file and may need to access any of
10Skia's headers. These libraries are each compiled with a different set of compiler flags
11(e.g. architecture options) and linked into the final library or binary.
