Subject: Move default seed setting to main().
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;h=ae912d6c208d27b897d6d43464e992e84c08cd33;p=vbig.git

Move default seed setting to main().

This will make it easier to change later and will simplify the seed
file option parsing which is to come.

No functional change.
