SNOW is a utility for concealing messages in ASCII text by appending whitespace to the end of lines. Because spaces and tabs are generally not visible in text viewers, messages concealed with whitespace are effectively hidden from casual observers. If SNOW's built-in encryption is used, the message cannot be read even if it is detected. SNOW exploits the Steganographic Nature Of Whitespace, similar to finding a polar bear in a snowstorm; hence the name.
TAP4Pascal is an easy-to-use but powerful unit testing suite for Pascal (FreePascal, Turbo Pascal, et al.), conforming to the Test-Anything Protocol (TAP) specification, originally developed for testing Perl, and lightweight enough to work on any platform since it is entirely text-based. It comes with its own test harness for running and summarizing the results of multiple test sets. It aims to be straightforward and to make test building easy and quick for developers, and to help software work better for everyone.
