# possible overrides:
#  OSE=1            force VBOX_OSE
#  NOPARALLEL=1     compile with -j1
#  LINUX=<dir>      compile vboxdrv against Linux found in <dir>
#  VERBOSE=1        verbose build
#  DEBUG=1          debug build
#  NOSUBVER=1       disable generation of the sub-version field (which is
#                   either the subversion rev [if available] or the build date)
#  NODOCS=1         don't build docs, use precompiled UserManual.pdf and
#                   VirtualBox.chm from $(vboxroot)/prebuild
#  NOMODS=1         don't build any module
#  NOQT=1           don't build the Qt GUI
#  NOSDL=1          don't build VBoxSDL
#  EFI=1            include the EFI binary from prebuild
#  VERSUFFIX=<suffix> set a particular package version suffix (e.g. _customer)
#  HEADLESS=1       build the headless version
#  VNC=1            build VNC code
#  NOWEBSVC=1       don't build the webservice API, default for OSE
#  STAGEDISO=<path> don't build the VBoxAdditions, use the precompiled .iso
#  PKGDIR=<path>    where to store the final package(s)
#  svn_revision=xxx do not depend on subversion being available, but use this
#                   hard-coded revision number instead
#
# NODOCS will also be set if UserManual*.pdf and VirtualBox*.chm are placed in
# $(vboxroot)/prebuild.  STAGEDISO will be set if VBoxGuestAdditions.iso is
# placed there.  Wine will not be required to be available if both NODOCS and
# STAGEDISO are set.
