wget-dos is a method that creates the fetch scripts for hosts running DOS, the
main target being FreeDOS. As a side effect, it will also work with Windows
based machines ;) After generating the scripts, you will get a warning which
binaries need to be installed on the target according to your settings. These
can be in PATH or simply in the same directory as the scripts. The easiest
possibility is to disable md5-checks, then you just need wget.exe. Still,
adding sha236sum.exe is also not that hard :) Locations for working binaries are:

wget   (DOS)  : http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/1.0/pkgs/wgetx.zip
md5sum (DOS)  : http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/1.0/pkgs/md5sumx.zip
wget   (Win32): http://users.ugent.be/~bpuype/cgi-bin/fetch.pl?dl=wget/wget.exe
md5sum (Win32): http://www.md5summer.org/md5sum.zip

Note that method-options like "tar" and "restart" are not (yet?) supported.
Thus, you also cannot use the update function of APT yet.
