duende - 2.0.13-1.4+deb11u1 main

The duende program starts a child process as specified on the command
line and handles some aspects of maintaining it as a daemon process.
In particular it passes the standard output and error from the child
process to syslog. If the child process exits with a configurable exit
status it will be restarted. Optionally duende will provide a pid file,
and other features are configurable.
