Hi, I'm creating a package for rnamotif. It has some force field data files that as they are architecture independent I'm putting them into /usr/share/rnamotif/enfdata. I need to setup an shell variable: ENFDATA=/usr/share/rnamotif/enfdata/ How must I do it? Shall I setup it somewhere or ask end user to setup itself? Debian policy 9.9 isn't clear enough for me :( Thanks, Adrian.
