penv is a utility which helps manage persistent per-directory environment settings. In other words, it saves you the trouble of setting or specifying the same environment variables over and over again when executing programs in a specific directory. The main reason for the initial development of penv was its use with the FreeBSD Ports Collection , but it may be used for other day-to-day tasks, too.
For its operation, penv needs to run an ``environment processor'' - a program that sets up the environment according to the contents of files in a given directory. By default, penv uses for its environment processor the envdir command from Dr. Dan J. Bernstein's daemontools package, available at http://cr.yp.to/daemontools.html.
