conda-forge.org: cylc-flow-base

Cylc ("silk") is a workflow engine for cycling systems - it orchestrates distributed workflows of interdependent cycling tasks that may continue to run indefinitely. There are two cylc-flow packages: * `cylc-flow`: The full installation, recommended for most uses. * `cylc-flow-base`: A minimal package, recommended for installation on job hosts where the full range of user-facing commands is not required. The `cylc report-timings` command requires two additional dependencies which you must specify manually if you want this functionality: * `pandas >=1.0,<2` * `matplotlib-base`
