new version of sem package

[John Fox]

Dear R-announce list members,

I've just uploaded to CRAN a substantially revised version (0.6-0) of the 
sem (structural-equations model) package. The new version uses a formula 
for the gradient to fit generalized SEMs, and also allows symbolic 
specification of the model.

As always, comments and suggestions are appreciated.

John
