# Looping Workflows
Scala Implementation of the workflow language with loops published in CSF '17.
Scala Implementation of the workflow language with loops published in CSF '17, CCS 18.
## How to use
To generate LTL formulas from non-omitting workflows, have a look at
``MainLTL``
.
To do First Order invariant inference, have a look at
``MainInvariantsInference``
.
## Parser
There is a working parser that can read the
``*.spec``
files in
``/examples``
.
