I\'ve been using bsdiff and i\'m very happy with it, and I want to try Google\'s Courgette.
It seems like a large effort to fetch/compile the entire Chromium project jus
I've tried all last night and today, grrhhhhh:(
You can download Courgette src (without the entire Chromium) https://chromium.googlesource.com/chromium/src/courgette/+/master and then use GN and Ninja to build it (on a Win7 x64 with VS2013 SP4, that hops on one leg in an anti-clockwise motion, clicking its fingers while patting its head and running off solar power...). However I followed the instructions exactly and kept getting errors.
It might be easier to email these guys requesting a copy: https://groups.google.com/a/chromium.org/forum/#!topic/chromium-discuss/dDUDnc9wXts or the new people who have taken ownership
I too am now determined to get Courgette.exe or be able to build it!
Thanks to @Mehrdad here is a copy of the 64-bit version of Courgette compiled on 2018-08-12 with this SHA256: 5cb2843588d2cbd9f0f558e7c6c3f86bf6b2ca249bfd6c452d742f5a724471be

Hopefully this will reduce the bandwidth of the internet significantly... in the many years to come... when file sizes get ridiculously large for simple updates. Thxs Google!
