-You should build out-of-tree by creating a build directory and configuring from
-there.
-
-Target selection:
-  --target=fx9860g|fxcg50
-
-  fx9860g covers all fx-9860G II-like monochromes models that support add-ins
-  or can be flashed with an OS that does. This includes SH3 and SH4 machines.
-  Default toolchain is 'sh-elf'.
-
-  fxcg50 covers just the fx-CG 50; there is some unofficial compatibility with
-  fx-CG 10/20. All of these are SH4-only.
-  Default toolchain is 'sh-elf'.
-
-Build options:
-  --toolchain=TRIPLET  Build with a different toolchain
-  --prefix=PREFIX      Install prefix (PREFIX/lib and PREFIX/include are used)
-  --cflags=FLAGS       Additional compiler flags at end of command
-
-Library options (disabled by default):
-  --no-syscalls        Cut off all syscalls (this will break things)
-                       Only use this option if you have a good idea of which.
-  --static-gray        Allocate gray VRAMs in static RAM instead of the heap
-                       May help when --no-syscalls is on.
-  --user-vram          Allocate VRAM in user stack; takes 350k/512k [fxcg50]
-
-Size limits:
-  --atexit-max=NUM     Number of exit handlers in atexit()'s array [16]
-
-Deprecated options (to be removed):
-  -events-queue-size=<n>
-                       Size of event queue (this mechanism is likely to
-                       disappear in future versions) [64]
