The aim of the project is to provide and maintain Mingw32 ports of the important OpenSource software packages, primarily libraries. Mingw32 is a Minimalist Gnu-Win32, GNU target to build native Win32 applications. The scope of the project not just gather distributions built in adhoc way, but rather to provide software with consistent and reproducible building procedure, as much as possible relying on existing standards (GNU autoconf/automake/libtool), consistent and elaborated (but not overcomplicated) packaging and straight installation procedure.
You can browse and download available packages from the Project Page.
