hmm.. yeah I use those guys a lot.. with grep also.. I think what might 
throw me off is things like def.orig = def.new then def.orig gets lost 
in the mix(or it's there, but the grep becomes gigantic in code 
results.) main thing I look for is googling "somedefinition linux man"
for some idea of what that function does.
