But change is under way: Note  Bill Rising`s talk at the Milan UGM 2008

The fact that -ssc hot, n(4)- throws up nothing but "translation" packages
is certainly not lost on StataCorp...

I think one disappointment with Stata is no package like Sweave for R  
or SASweave for SAS for weaving together publication quality text,  
code, output, and figures into one file, more or less seamlessly. HTML  
output is also good thing. I have used and appreciated log2html.  
Improvements would be great. ATS also had an HTML package that worked  
figures in, but I think it stopped working. It would be nice to have  
HTML and LaTeX output, but HTML at minimum.
