# The build system expects packages to be extracted to

# Try to strip the top level dir from the archive and extract to
# the correct directory if possible so packages don't need to
# set PKG_SOURCE_DIR and scripts/unpack doesn't need to rename
# the directory.
# Currently this is only supported for tar archives.
# If PKG_SOURCE_DIR is set don't apply any directory mangling
# so advanced renaming (eg stripping more than one directory level)
# can be performed by scripts/unpack.
