12#
13# The comprehensive enumeration of QEMU system emulation ("softmmu")
14# targets. Run "./configure --help" in the project root directory, and
15# look for the *-softmmu targets near the "--target-list" option. The
16# individual target constants are not documented here, for the time
17# being.
18#
19# Notes: The resulting QMP strings can be appended to the "qemu-system-"
20#        prefix to produce the corresponding QEMU executable name. This
21#        is true even for "qemu-system-x86_64".
