[d2n-analysis-talk] DB/, analyzer, and replay/ updated on d2n and in CVS

[Diana Parno]

Thanks, Dave! Your explanation was both very cogent and very directly 
useful: I managed to fix my problem. I hadn't realized that StartType.pl 
moves the relevant files into my working directory -- it was those DB 
files (which must have been there from a previous analysis) that the perl 
script was complaining about not being symlinks. I moved those files out 
of my working directory, and the analysis is now running happily. So there 
was no problem with the DB files, or with the StartType script -- it just 
expected something from my working environment that I hadn't known to 
provide.

Much appreciated!
