smd-loop runs smd-push and smd-pull at regular intervals as defined by the user in the ~/.smd/loop
configuration file. On errors that are reported to be transient, it retries a second time before failing.
The configuration file is line-oriented. Each line is composed of three space separated fields: pull-
frequency, push-frequency and endpoint-name. Frequencies are expressed in minutes, while endpoint name is
a valid name for smd-pull(1) and smd-push(1). Lines beginning with # are considered as comments. The
following example calls the command smd-pull default every 3 minutes, and smd-push default every 10.
Example:
# pull-frequency push-frequency endpoint-name
3 10 default
