Version 1.2.1 of the CACTVS tools collection has been released. This is a collection of Tcl/Tk-based scripts running on a generic chemistry-aware data manager program. Among the tools are a full-featured 2D structure editor, a 2D structure browser, an IR spectra display tool and a number of additional goodies.

Information about the context of these tools as well as downloading instructions can be obtained from http://schiele.organik.uni-erlangen.de/cactvs/index.html This is a binary-only release. Precompiled executables are provided for SunOS4.1, Solaris2.4 and Irix5.3. Versions for Linux and HPUX can be expected sometime later.
