Command line interface is trivial enough to allow non-interactive builds..
e.g.:
#! /bin/bash
xst -ifn ${project}.xst -ofn ${project}.syr
ngdbuild -dd . -uc ${project}.ucf ${project}.ngc ${project}.ngd
map -o ${project}_map.ncd ${project}.ngd ${project}.pcf
par -w -ol high -t 1 ${project}_map.ncd ${project}.ncd ${project}.pcf
bitgen -w -d ${project}.ncd ${project}.bit
promgen -w -u 0 ${project}.bit -p bin -o ${project}.bin

If you read the Xilinx license.txt, you will find it goes on at length
about "copyrighted material", "trade secrets", "proprietory information",
and "Intellectual Property". Section 2 make interesting reading along side
the GPL text..
I dare say Altera's software would also provide conflicts in licensing
conditions.. N.M.P.
