Can ircampack be treated as "obsolete" (ie can I put it in applications/obsolete rather than applications)? Can I also assume that the vecplot and segment commands can be removed completely, even from the obsolete import? Why do they exist? They seem to be the old kappa versions. Does anyone actually use ircampack? The build is complicated by its desire to link against libkapsub BUT that requirement disappears if SEGMENT is binned. David - can you remember why there are private versions of SEGMENT and VECPLOT in ircampack? -- Tim Jenness JAC software http://www.jach.hawaii.edu/~timj
