... A collection of codes is compiled for studying some aspects of the large scale clustering of galaxies, clusters and superclusters of galaxies. ... That is why a package of codes for large scale structure analysis cannot be written as a general tool. Nevertheless, a collection of procedures for studying some aspects of the clustering in the Universe can be constructed; inevitably any such package or collection of codes will only be a starting point and will require additional development. ...
