I looked at the page you sent; the part about features is under the 
"properties" heading.  The feature you mentioned is not listed on either 
that page of the "Builtin features" link off that page.  I had searched 
for things like "boost build set feature on command line" (the link you 
sent is the third result, but the others don't say anything about setting 
features on the command line, only in Jamfiles).  I don't think it would 
be obvious from the link how to set features (or that 
preserve-test-targets is a feature at all, or what its possible values 
are).  A brief skim of the Google results (like I did to try to answer my 
question originally) would not have shown that the link you gave me would 
be useful.  Thank you for showing me that page, though.
