libembryo-dev 1.8.6-2ubuntu1 (amd64 binary) in ubuntu utopic

 Embryo is primarily a shared library that gives you an API to load
 and control interpreted programs compiled into an abstract machine
 bytecode that it understands. This abstract (or virtual) machine is
 similar to a real machine with a CPU, but it is emulated in
 software.
 .
 This package contains headers and static libraries for Embryo.
