Transport from California? That is especially generous of you!

Not entirely sure what prompted this rude reply. But GMP-ECM, when linked against the gwnum library, will auto-detect some numbers of the form k*b^n+c and k*b^n-c and automatically use the faster gwnum_ecmStage1(), at least in some cases.
