Putting Rcov to work in program, the FAQ gives the following as the  
basic procedure:

require ‘rcov’  
rcov\_analyzer = Rcov::CodeCoverageAnalyzer.new  
at\_exit do  
rcov\_analyzer.remove\_hook  
rcov\_analyzer.dump\_coverage\_info([Rcov::TextReport.new])  
# use Rcov::HTMLCoverage above to generate HTML reports; the  
formatters admit  
# a number of options, listed in rcov’s RDoc documentation.  
end  
rcov\_analyzer.install\_hook

That does the job for the analysis, but how do I generate the HTML  
reports now? How do I use Rcov::HTMLCoverage as the embedded comment  
suggests? I tried

```
  Rcov::HTMLCoverage.new.execute

```

But that did nothing (which doesn’t surprise me since it has no  
reference to rcov\_analyzer).
