it also accepts slightly modified files... rather than each line being a number, it pulls numbers in pairs. the first line holds the k, the second the n value.
I think GMP-ECM has expression expansion already. At least the 5.1-beta that I got from the Yahoo PrimeNumbers Group would accept expressions like 4847*2^300087+1.
