# the source archive.  It makes packaging and scripting all play happily.

# With Linux 3.x, it always has a 3 digit number - e.g. 3.2.0 rather than just 3.2:
#export VERSION=${VERSION:-4.3.5}
export VERSION=${VERSION:-4.4.14}

# The architecture name component of the .t?z package file name:
# This used to be "noarch" but it's a package of the kernel source tree that
# has been compiled for ARM, so I believe it should be tagged by architecture.
# Let this be set by the defaults.  Can be overridden below if need be in the future.
