promgen: An easier way to generate .bit.bin

Some weeks ago I came across a simpler way to generate the binary bitstream file. I hadn't gotten around to trying it and testing it until tonight.
It is easier than the bootgen method in that no .bif file needs to be created, nor is a dummy.elf required. It goes straight from .bit to .bit.bin with no messing around.
I did a search on the forum and saw no references to promgen, so I thought I should share it.
promgen -b -w -p bin -data_width 32 -u 0 parallella_z7_top.bit -o parallella.bit.bin
Is anyone familiar with this tool and know of any issues with it?
