I generated the factor-base file by running the cado-nfs script and letting it call makefb for me, then transcribed the command lines in L2253.wucmd to get raw las command lines.

/scratch/cado-gnfs/cado-nfs-2.3.0/build/oak/sieve/makefb -poly L2253.jon/L2253.poly -lim 268000000 -maxbits 16 -out L2253.jon/L2253.roots.gz -t 40
seems to be the command line for makefb

L2253.poly is just as for gnfs-lasieve4I15e except that it's just the polynomial and no sieving parameters:
