similarity-utils is a set of two programs to give a quantitative measure of how similar two files are, on a scale 0 to 1. similarity_by_diff measures the number of difference lines reported by diff(1), while similarity_by_zlib tries compressing the two files, both separately and together, and comparing the results.

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.
