+ as conformer sampling program, hence the abbreviation Conformer–Rotamer Ensemble Sampling Tool,
+ but now offers also some utility functions for calculations with the GFNn–xTB methods. Generally
+ the program functions as an IO based OMP scheduler (i.e., calculations are performed by the xtb
+ program) and tool for the creation and analysation of structure ensembles.
