I thought more about it and looked at the code more. There are many common part of code that I rather not to separate. Besides it adds to much unneeded complexity to the source, gyp files and ebuilds.

If we want a simple example, then we should write a simple one instead of complicating the other ones. If you really need it to be three executables. I can set up macros that creates three executables based on parameters in the gyp file. But even that I don't really see it necessary.

I guess we don't need 3 separate binaries, but it would be awesome to have a target that the fuzzed only format, so that the main example fuzzer isn't flawed in any way.

Would you mind creating another target, let's say "puffin_huff_fuzzer" that only called FuzzHuff. This could be used as the primary example fuzzer without accidentally teaching people not-great practices.

I suppose you could keep the call to FuzzHuff in puffin_fuzzer, or you could remove it (which is preferable) but what happens here is less important since it isn't going to be the primary example fuzzer.

I had in mind to create a new fuzzer for bsdiff program (https://cs.corp.google.com/chromeos_public/src/aosp/external/bsdiff/). That would only have one function: bspatch(). Would that be something you would be interested instead?

Sure. Sounds good.

Thanks!

submitted aosp/663027 for review. Will send the ebuild stuff after it lands.
