The Statalist FAQ advises: 

Say what command(s) you are using. If they are not part of 
official Stata, say where they come from: the STB/SJ, SSC, 
or other archives

In this case, -findit wls0- finds a program by Phil Ender. 

. type http://www.ats.ucla.edu/stat/stata/ado/analysis/wls0.ado

In addition to the help file for -wls0-, the .ado file is its 
own best documentation. Fire up your favourite text 
editor, and all is there for inspection.
