Tux Paint is available in 'pkgsrc', a framework for building third-party software on NetBSD and other UNIX-like systems (Solaris, Linux, FreeBSD, OpenBSD, HP-UX, QNX, Haiku, etc.).
It is divided into three parts, which you can learn about at "pkgsrc by the web", pkgsrc.se.
- Tux Paint
The core program and data-files (user interface graphics, sound effects, etc.)
- Tux Paint Config.
The graphical configuration tool for parents and teachers.
- Rubber Stamps (optional)
A collection of 'rubber stamp' images (and corresponding data and sound effects) for the "Stamp" tool.

Did you know? Tux Paint is not shareware, it's open source. So it's free, forever!
