5Description: png compression/decompression library
6Local Modifications: (1) Created pnglibconf.h from pnglibconf.h.prebuilt (a
7 rename with a few additional settings enabled). (2) Copied LICENSE into
8 this directory. (Originally it was pulled from png.h, but libpng has
9 now provided a separate LICENSE file for convenience, which we use
10 directly.)

12FAQ:
13Q: Why does this directory exist?
14A: libpng is pulled in through DEPS, but in order to build it using ninja, we
15 need to create pnglibconf.h. We originally tried creating
16 the file as an action in https://codereview.chromium.org/930283002/, but this
17 apparently led to a race condition on Windows, where some builds failed to
18 create the file in time for other files to include it. By checking these
19 files directly into Skia, we eliminate the race condition.
