The program suite has been implemented on a large number of hardware platforms including Unix. Installation is straightforward and full instructions are given in the BLANC manual.
The BLANC program suite is licensed free to academic institutes. The programs may be obtained by Internet ftp from anonymous@ftp.ucmb.ulb.ac.be. (First read file: pub/alexei/blanc/README). Several programs and superprograms independent from the BLANC suite (SFCHECK, MOLREP, CONTACT, MAKECIF, EMIN, LIBCHECK etc.) are kept in separate directories at the anonymous ftp site. Separate arrangements can be made for commercial organisations. For further details contact Dr.A.Vagin (email: alexei@ucmbcx1.ulb.ac.be).
