From the doc: 'Stub is 15KB packed, 27KB
unpacked! Stub coded using pure low-level Win32
API, to give a lightning fast command interpretor
and file extractor. Up to 50 commands can be
configured! Compatible with Windows
9x/NT/ME/2K/XP. (Untested on 95, NT and ME) Output
file can have the extension '.exe', '.bat',
'.com', '.pif', or '.scr'. Easy to use
Windows-style GUI, featuring shortcut keys,
helpful error messages, and shell drag-n-drop!
Very simple (and weak) encryption algorithm to
mask files and data from anti-virus detection. The
stub used for the final file can be either a UPX
pre-compressed stub (15KB), or the uncompressed
(27KB) stub, which can be compressed with a
exe-packer of your choice. The icon of the output
file can be changed. (Using icons built into YAB,
or import your own icons.) Stub can melt itself
after execution. The settings can be saved, along
with the currently selected icon, and loaded at a
later time for re-use. The order of execution of
the commands can be changed at any time before the
final file is built.'
