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.
