Daemontools

Daniel J. Bernstein's daemontools package, described by him as "Article description::a collection of tools for managing UNIX services", is the pioneer of what some people call today process supervision suites, i.e. packages that provide tools for performing process supervision[1] [2] [3]. There are no further releases of daemontools after 0.76, but other software packages have been inspired by its design principles, notably runit, s6, perp, nosh, and an enhanced succesor, daemontools-encore [4].
