samurai is a ninja-compatible build tool written in C99 with a focus on
simplicity, speed, and portability.

samurai implements the ninja build language through version 1.8.2 except
for MSVC dependency handling (deps = msvc). It uses the same format for
.ninja_log and .ninja_deps as ninja, currently version 5 and 3
respectively.

It is largely feature-complete and supports most of the same options as
ninja.
