This program is a command-line helper for the fxSDK, a set of tools used in
conjunction with gint to develop add-ins for CASIO fx-9860G and fx-CG 50.

${R}fxsdk new${n} ${g}<FOLDER>${n} [${R}--makefile${n}|${R}--cmake${n}] \
[${g}<NAME>${n}]
  Create a new project in the specified folder. The default build system is
  CMake. Project name can be specified now or in the project files later.

${R}fxsdk${n} (${R}build${n}|${R}build-fx${n}|${R}build-cg${n}) [${R}-c${n}] \
[${R}-s${n}] [${R}--${n}] [${g}<ARGS>${n}...]
  Build the current project for fx-9860G (usually for .g1a add-ins) or fx-CG 50
  (usually for .g3a add-ins). The first form compiles in every existing build
  folder, and configures for both if none exists.

  With -c, reconfigure but don't build (CMake only).
  With -s, also sends the resulting program to the calculator.
  Other arguments are passed to CMake (if using -c) or make (otherwise). You
  can pass -c or -s to CMake/make by specifying --.

${R}fxsdk${n} (${R}send${n}|${R}send-fx${n}|${R}send-cg${n})
  Sends the target file to the calculator. Uses p7 (which must be installed
  externally) for fx-9860G. Currently not implemented for fx-CG 50, as it
  requires detecting and mounting the calculator (same for the Graph 35+E II).
