Eunice was one of several Unix compatibility packages developed during the 1980s. It provided VMS binary versions of Unix tools, a VMS object library emulating the Unix API (including the system call interface) and an assembler that produced VMS binaries.^[3] Eunice was criticized for its performance problems and not quite complete Unix compatibility.^[1] Eunice's reputation for poor compatibility inspired the "Congratulations. You aren't running Eunice." message included in the Perl configure script.^[4][5]
