Amoeba -- the constraint solving algorithm in pure C
Amoeba is a pure C implement of Cassowary algorithm.
Amoeba use Clean C, which is the cross set of ANSI C89 and C++, like
the Lua language.
Amoeba is a single-file library, for more single-file library, see the
stb project here.
Amoeba largely impressed by kiwi, the C++ implement of Cassowary
algorithm, and the algorithm paper.
Amoeba ships a hand written Lua binding.
Amoeba has the same license with the Lua language.
