       fxsdk (send|send-fx|send-cg)

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.

Project creation:
  fxsdk new <folder>

  Creates a new project in the specified folder. Project info is input
  interactively. Creates <folder name> and populates it with default project
  data.

Compilation:
  fxsdk build [-s]
  fxsdk build-fx [-s]
  fxsdk build-cg [-s]

  Compiles the current project for fx-9860G (.g1a target) or fx-CG 50 (.g3a
  target). With 'fxsdk build', compiles every existing build folder, and ask
  interactively if none is found.

  With '-s', also sends the resulting program to the calculator.

Installation:
  fxsdk send
  fxsdk send-fx
  fxsdk send-cg

  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).

Project update:
  fxsdk update

  Copies the latest version of the Makefile to your project. *This will
  discard any changes made to your Makefile.* If you have edited your
  Makefile, make a backup and merge the changes after updating.
