28"""Placeholder HTCondor DAGMan API.
30There is new work on a python DAGMan API from HTCondor. However, at this
31time, it tries to make things easier by assuming DAG is easily broken into
32levels where there are 1-1 or all-to-all relationships to nodes in next
33level. LSST workflows are more complicated.

335 the number of HTCondor rescue DAGs in the submit directory.

351 Maximal number of backups. If the number of backups reaches the limit,
352 the last backup files will be overwritten. The default value is 100
