+To build the applications in this directory, you should be able to run these
+target scripts in this order:
+
+./sandbox_build_all.sh
+	this will build all the applications
+	
+At this point everything should be built.
+
+Description of directory contents:
+
+sandbox_build_all.sh
+	target script to build all applications and libraries
+
+target_build_app.sh
+	target script to build one application
+
+target_build_lib.sh
+	target script to build one library
+
+clean_all.sh
+	target script to clean all build objects
+
+create_input_waveforms.sh
+	target script that executes waveform creation applications and
+	duplication scripts to create all input waveforms for the applications
+	to consume
+
+duplicate_x8.sh
+	this target script duplicates a file x8 times.  This is	used to
+	replicate the fundamental waveforms into longer patterns
+
+overhead.c
+	this is the source for the overhead library that all of the applications
+	are linked against
+
+fftdma_256.c
+	this application uses the FPGA logic to implement the FFT
+	algorithm for a variety of input sample sizes.  This variant moves
+	the input samples into the FPGA and the results back out using DMA
+	through the ACP port of the Cortex A9 processor
+
+neon32_256.c
+	this application uses the NE10 NEON functions to implement the FFT
+	algorithm for a variety of input sample sizes with 32-bit resolution
+
+create_real_short_sine32.c
+create_real_short_square32.c
+create_real_short_triangle32.c
+	these applications create the initial 32 samples of their respective
+	waveform, sine, square and triangle
+	
+real_short_to_ne10cpx_long.c
+	this application translates the real short data format into ne10cpx
+	long and short format which is consumed by the demo applications
+	
+ne10cpx_long_to_text.c
+	this application translates the ne10cpx long and short format binary
+	data into text format output which may be read by gnu plot for example
+
