DFT codes

[<jamejias "-at-" obelix.cica.es>]

     Dear netters
       I would like to hear about DFT codes. I woulk like to know
    about capabilities, advantages and drawbacks of the different
    programs availables. Are they freely distributed or not?
     Do they have pseudopotentials or something useful to handle
   with atoms such as gold or mercury?
     I am interested in molecular calculations as well as band
     structure calculations for solids and interfaces
     Of course, I'll summarize to the net.
     thanks in advance.
