LAP: A Little Language for OS Emulation

LAP, the Linux Application Platform, is a Linux emulation package for BSD/OS which uses a "little language" [Salu98] to describe transformations from Linux data types and values to BSD/OS data types and values, and vice versa. The little language simplifies and regularizes the specification of transformations, making the emulation easier to maintain. This paper describes the language and its place in the framework of LAP.
