Subject: RE: What's wrong with dynamic_7

I would like to trash dyna7, but have not yet.  I would consider it strongly
deprecated.  Dyna6 should be used instead.

If you want to do anything with it, you MUST use the separator switch.

./john --format=dynamic_7 --test

$ ../run/john -test=0 -form=dynamic_7 --field-sep=_
using field sep char '_' (0x5f)
Warning: doing quick benchmarking - the performance numbers will be
Benchmarking: dynamic_7: md5(md5($p).$s) (vBulletin) [128/128 SSE2
intrinsics 10x4x3]... DONE
Many salts:     240000 c/s real, 240000 c/s virtual
Only one salt:  120000 c/s real, 120000 c/s virtual

Also, adding a -list=list or -list=help would help a lot for people that do
NOT know the -list= options, vs simply stating to 'read OPTIONS'
