I shuold just mail quanstro I guess but maybe someone made a tool

/n/sources/contrib/quanstro/src/vblade

The vblades served by this particular vblade require some magic in the
first few bytes.
Vblade on other platforms will quite happily serve a bunch of zeros

Anybody got a script for making an empty vlbade image for serving with
the above vblade ?

Save me making one
