##
# @SysEmuTarget:
#
# The comprehensive enumeration of QEMU system emulation ("softmmu")
# targets. Run "./configure --help" in the project root directory, and
# look for the *-softmmu targets near the "--target-list" option. The
# individual target constants are not documented here, for the time
# being.
#
# Notes: The resulting QMP strings can be appended to the "qemu-system-"
#        prefix to produce the corresponding QEMU executable name. This
#        is true even for "qemu-system-x86_64".
#
# ppcemb: dropped in 3.1
