Because of the various package management systems we support, the pbutils tool was developed to help automate the package build process. As all packages install into a separate directory with a common installation base (e.g. /opt/TWWfsw/package), the pbutils tool is optimized to build packages for software organized in this manner. The XML-based package definition file defines the installation name, configuration files, dependencies, startup scripts, and wrapper scripts. Instructions for each package management system is contained in the same description file.

Below is a sample run of pb on Solaris for OpenSSH 4.0p1. Package description files for all of our packages, per release, is available online.
