registry::installed function

[Randall Wood]

The registry installed function returns a list of lists, the  
structure of which I don't understand to my satifaction. Given the  
two resulting entries returned by install, I gather the following:

     "pidgin 2.0.2 0 +msn 1 0",
     "pkgconfig 0.22 0 {} 1 0",

The string is "$name $version $revision $variants $active $whatIsThis"

$variants seems to be either an empty list, a string with a single  
variant, or a list or variants
I do not know what $whatIsThis is. Looking at the source code of $ 
{prefix}/share/macports/Tcl/registry1.0/receipt_flat.tcl it seems  
that  $whatIsThis is always a zero. What is it?
