Options to set flags of homotopy solver are not visible in the documentation

[Francesco Casella]

I tried to track the parameters Bernhard was showing in his OM Workshop presentation. I managed to get ​--homotopyApproach,but I failed to locate all other parameters.

The ​Sphinx job that builds the documentation is often broken, but it ran succeessfully last time on Feb 1st, so I understand everything related to homotopy should be included.

Please check if those options are included and if so, please notify here where they can be found. Some cross-references in homotopyApproach could be useful.

The homotopy flags are simulation flags and can be found here:
