They are:

• portable, no installation required and they run on external media (USB stick),
• stealth, the registry is not used and they leave no traces in the host-PC,
• possibly settings are written into the application folder,
• 32bit programs and run under (almost) all Windows versions,
• in english, possibly with a german language file (*.DE) and a help in german with a bad machine (!) english "translation"
• otherwise with a short english help (for "command line utilities" by running without parameters).

Comments and suggestions are welcome ...
