-If you are installing Frobby as a dependency, most probably you only

-----------------------------------------------------------------------
-
-Warning: the library documentation is very incomplete.
-Warning: installing documentation might require high build times due

-
-----------------------------------------------------------------------
-
-Warning: hilbert_deform and hilbert_bigatti tests are known to fail
-because simplifications do not work for action "hilbert" with

-expressions such as "a*b*c + a*b*c" or "a - a". Nevertheless results
