eywords within the DFT module input directive, <code>XC slater vwn_5</code>.

<P>
That is, this statement in the input file
<PRE>
dft
  XC slater vwn_5
end
task dft
</PRE>

<P>
is equivalent to the simple line
<PRE>
task dft
</PRE>

<P>
The <code>DECOMP</code> directive causes the components of the energy
corresponding to each functional to be printed, rather than just the
total exchange-correlation energy which is the default.  You can see
an example of this directive in the sample input in 
Section <A HRE
