cf-execd - scheduling daemon for cf-agent
cf-execd is the scheduling daemon for cf-agent. It runs cf-agent locally
according to a schedule specified in policy code (executor control body).
After a cf-agent run is completed, cf-execd gathers output from cf-agent, and
may be configured to email the output to a specified address. It may also be
configured to splay (randomize) the execution schedule to prevent synchronized
cf-agent runs across a network.

CFEngine provides automated configuration management of large-scale computer
systems. A system administrator describes the desired state of a system using
CFEngine policy code. The program cf-agent
reads policy code and
attempts to bring the current system state to the desired state described.
Policy code is downloaded by cf-agent
from a cf-serverd
The daemon cf-execd
is responsible for running cf-agent
Documentation for CFEngine is available at http://cfengine.com/documentation/.
CFEngine is built on principles from promise theory, proposed by Mark Burgess in
2004. Promise theory is a model of voluntary cooperation between individual,
autonomous actors or agents who publish their intentions to one another in the
form of promises. A promise is a declaration of intent whose purpose is to
increase the recipient's certainty about a claim of past, present or future
behaviour. For a promise to increase certainty, the recipient needs to trust
the promiser, but trust can also be built on the verification that previous
promises have been kept, thus trust plays a symbiotic relationship with
