+ To list *all* boards, do this: ./build roms list
+
+ Optional Flags:
+ -d: displaymode
+ -p: payload
+ -k: keyboard layout
+
+ Example commands:
+
+ ./build roms x60
+ ./build roms x200_8mb x60
+ ./build roms x60 -p grub -d corebootfb -k usqwerty
+
+ to see possible values for 'target':
+
+ ./build roms list
+
+ Can also build serprog images:
+ ${serprog_usage}
+
+ to see targets of only a given status (stable, unstable,
+ broken, untested and unknown), try e.g.
+
+ ./build roms list stable
+ ./build roms list unstable untested
+ ./build roms list unknown
+ ./build roms list broken
+ ./build roms list broken stable
+
+ the value is set in target.cfg for each board. if status
+ is unitialised, it defaults to "unknown". only stable/unstable
+ targets are permitted in releases; broken, untested and
