#
# @qemu.micro:  The micro version of QEMU.  By current convention, a micro
#               version of 50 signifies a development branch.  A micro version
#               greater than or equal to 90 signifies a release candidate for
#               the next minor version.  A micro version of less than 50
#               signifies a stable release.
#
# @package:     QEMU will always set this field to an empty string.  Downstream
#               versions of QEMU should set this to a non-empty string.  The
#               exact format depends on the downstream however it highly
#               recommended that a unique name is used.
