Yes, the application is freely available (GNU/GPL) - it's the FreeDOS package manager: http://fdnpkg.sourceforge.net/ The latest source code is on the svn here (includes my i386 build of watt32): http://sourceforge.net/p/fdnpkg/code/HEAD/tree/ cheers, Mateusz On 12/12/2013 02:06 PM, Juan Manuel Guerrero wrote: > Am Dienstag, 10.
