description             Linux ABI implementation for macOS

long_description        Noah is a Darwin subsystem for Linux. Noah is \
                        implemented as a hypervisor that traps Linux \
                        system calls and translates them into Darwin \
                        system calls. Noah also has an interpreter of \
                        ELF files so that Linux binary executables run \
                        directly and flawlessly without any \
                        modifications. It's effectively a macOS Linux \
                        execution flavor, similar to that of FreeBSD \
                        Linuxolator, a.k.a. Linux emulation, a.k.a. \
                        Linux ABI. In other words, it's the reverse of \
                        the Linux Darling project.
