The ARM port of SliTaz is ready. The community has developed a new tool sat (SliTaz ARM Tool) for building custom distros. Currently it works on the Raspberry Pi and provides a GUI. The ARM post has its own version of the cooker: ARM Cooker to ease the development. spk is the ARM Package Manager. Packages are uploaded in the Hg repository. Pre-built toolchains are available for cross-compilation or a developer can even make his own toolchain using the cross tool. The ARM emulator (based on qemu) is also available among the packages.
I think it is a great step for SliTaz as it increases the chances to be ported on ARM based mobile devices.
