The documentation is terrible, it totally unclear whether .bp or .mk
files are used. Maybe .bp file are transistional files only. Who knows?

For platform/system/core [1] there is a .bp file (and a .mk file), but
for e.g. fastboot (which is part of system/core) [2] there is only a .mk
file, while for soong there is a .bp file again [3]

Interesting (just discovered):

After running "repo sync" the directory .repo/projects/build contains
blueprint.git, kati.git, make.git and soong.git. So I assume there are
the tools to start with.

  * kati – https://android.googlesource.com/platform/build/kati

    based on Makefile (two others will be ncluded), implemented in C and Go
    .travis.yml available, is building the C implementation
    build seems to require ninja (according to travis.yml), but makefile
    does not use it
    tests require ruby
    .rravix.yml seems to run more tests than test-target

  * blueprint – https://android.googlesource.com/platform/build/blueprint

    .travis.yml available
    build seems to require ninja and go (according to travis.yml)

  * make – https://android.googlesource.com/platform/build

    Seems to include a lot if Makefiles to be included by Makefiles.
    There is a README. Scanning ofer this I assume, that this is the
    "meta-make" for building the android platform (commands m, mm, mmm).

  * soong – https://android.googlesource.com/platform/build/soong/
