WinLess is a small utility for Windows that can show inside its own window anything passed to its standard input and optionally replicate it to standard output (essentially acting as a probe). It is useful as an alternative to the more command that comes with Windows and to pagers like less and most - but instead of running inside the console, it uses its own window with some additional commands (like search, print, save, etc).
The program is written in Delphi 2 and is open source licensed (but note) under the zlib license. It should be trivial to port it to Lazarus, although i chose Delphi 2 because it creates a very small executable.
For usage info see the readme.txt file.
