MD5 checksum utility

A little MD5 CHeck sum utility to check the integrity of a downloaded file is available at fourmilab.
I just pasted the md5.exe in my download folder. And from a DOS command prompt, the command "md5.exe filetoanalyse" will return the checksum. For example:

C:\user\Downloads>md5.exe py2exe-0.6.9.win32-py2.6.exe

Returns

F05FD1F17B1473A13E1919D6D7FA0B08 py2exe-0.6.9.win32-py2.6.exe
