My thread is about extracting useful info from PL using SQL (since PL provides no formal hooks to its internal workings). The tools I have provided so far all deal with keywords.
If your keyword system is external to PL, then the tools are of no use to you. If you use PL’s database for keywording, then they are. Arguments about which approach is superior are irrelevant in this thread. If you’d like to argue about the merits of one approach vs. another, please start your own thread on the topic.
