su-wrapper Runs Programs as Another User and Group
su-wrapper is a little utility that allows special users to execute
processes under another uid and gid.
It uses a table (/etc/su-wrapper.conf) to decide whatto do in certain
situation. Therefore it walks through the table and tries to match the
current situation (the later entries have precedence).
For more information, read /usr/share/doc/packages/su-wrapper/README.
