		Import a Xilinx TCL board initialization file as an Oberon module suitable for use in the Zynq Bootloader.

			- ps7_pll_init_data_*
			- ps7_clock_init_data_*
			- ps7_ddr_init_data_*
			- ps7_mio_init_data_*
			- ps7_peripherals_init_data_*
		where the * is 1_0, 2_0 or 3_0.
		These sections are placed in a module named FsblInit as matharray constants. These constants are then used
		by the Initializer of the bootloader.

		Syntax:
			ZynqTools.ImportTCL [-d=dir|--directory=dir] [-m=moduleName|--module=moduleName] boardName file ~
		board: name of the board
		file: TCL file name
		-d|--directory gives the output directory.
		-m|--module gives the module name (default TclInit).
