# This script is for converting code inside the vboxvideo module to Linux
# kernel coding style.  It assumes correct VirtualBox coding style, will break
# break if the coding style is wrong (e.g. tab instead of spaces) and is not
# indended to be a generic solution: for example, identifiers will be
# translated case by case, not algorithmically.  It also assumes that any
# flexibility in either coding style will be used where possible to make the
# code conform to both at once.

# Replace up to six leading groups of four spaces with tabs.
