Code coverage for PL/SQL

Question

Does anyone have tools or experience with code coverage for PL/SQL. I believe this is possible using DBMS_PROFILER?

I found something useful on http://www.databasejournal.com/features/oracle/article.php/10893_2197231_3 page.

select exec.cnt/total.cnt * 100 "Code% coverage"
from  (select count(1) cnt
      from plsql_profiler_data d, plsql_profiler_units u
      where d.runid = &&runid
      and u.runid = d.runid
      and u.unit_number = d.unit_number
      and u.unit_name = upper('&&name')
      and u.unit_owner = upper('&&owner')
      ) total,
     (select count(1) cnt
      from plsql_profiler_data d, plsql_profiler_units u
      where d.runid = &&runid
      and u.runid = d.runid
      and u.unit_number = d.unit_number
      and u.unit_name = upper('&&name')
      and u.unit_owner = upper('&&owner')
      and d.total_occur > 0) exec;
