 # there do not seem to be any tests include with this port. 'make check' does nothing.
 
 # Other options that could be considered here:
-#--enable-occ            compile with OpenCascade geometry kernel
-#--enable-nglib          generate shared library nglib
 #--enable-parallel       enable mpi parallelization
 #--enable-jpeglib        enable snapshots using library libjpeg
 #--enable-ffmpeg         enable video recording with FFmpeg, uses libavcodec
 #--enable-mkl            link Intel's mkl library, necessary for ngsolve and mkl 11.x
 #
 #Optional Packages:
-#--with-occ=dir          use OpenCascade installed in directory dir
 #--with-togl=dir         directory containing libTogl1.7
 #--with-metis=dir        path to metis 5.x
