class Vacuumms(CMakePackage):
    """VACUUMMS: (Void Analysis Codes and Unix Utilities for Molecular Modeling and
    Simulation) is a collection of research codes for the compuational analysis of
    free volume in molecular structures, including the generation of code for the
    production of high quality ray-traced images and videos. Note that production of the
    images from the generated code is considered post-processing and requires POVRay
    and feh (on X11 systems) as post-processing dependencies. VACUUMMS has been tested
    under Linux on x86_64 and ARM64. Please submit questions, pull requests, and bug
    reports via github. https://dl.acm.org/doi/abs/10.1145/2335755.2335826"""
