Do178Builder is a documentation tool used throughout the software/hardware development effort, helping to produce the DO-178B/254 documentation much less painfully. A major obstacle to creating airborne products, for smaller developers, is the necessity to qualify the software per RTCA/DO-178B, or hardware per RTCA/DO-254. Without this qualification, airborne products cannot be deployed.
Trowser is a browser for large line-oriented text files (such as debug traces). It's meant as an alternative to "less". Compared to less, trowser adds color highlighting, a persistent search history, graphical bookmarking, separate search result windows, and flexible skipping of input from pipes to STDIN. Trowser has a graphical interface, but is designed to allow browsing via the keyboard at least to the same extent as less. Key bindings and the cursor positioning concept are derived from vim.
