Source codes are under univm.net folder.
Currently .Net version is the most complete implementation. It includes the VM and assembler, they are univm and univmc.
This implementation heavily depends on unsafe and pointers to improve performance and save memory/gc. Almost like writing in C. ;-P
build-bflat.sh build with bflat but only build univm.
Source codes are under univm.c folder.
Currently, C version is not working and no plan of implementing assembler in C.
C version aims on maximizing compatibility. Currently almost only use C99.
Build script are written in ash-compatible shell script.
