Difference between \parskip and \parsep ?

[Steve Litt]

Hi all,

I've been trying to figure out the difference between \parskip and \parsep. 
What I've come up with so far is that \parsep operates only within lists, 
while \parskip operates only outside of lists. Is that true, or have I 
misread?

Thanks
