This is great news.

I can rewrite that to be more prose than > this sort of auto-documentation format. Is there a python documentation generator that can process that and do something sensible with it? If so, I'm fine with it. If not, then maybe the @type bits can be combined into the @param somehow (yes, it would just be text then). > I wasn't sure of how/where to update the documentation. Greg? Do you have > an idea of where it might go? Or perhaps want to do it yourself? The API docs are automatically generated. It would be nice to have a brief section for the GettingStarted document ($RDBASE/Docs/Book/GettingStartedInPython.rst), but I am willing to write that if you don't have time. > In other news, I'll be presenting the MCS work at the Goslar conference > this fall, and I've got some funding to work on finding a threshold MCS, > that is, the maximum common substructure which is in at least some percentage > threshold of the entire system. Congrats! That would definitely be useful. > Can anyone suggest a good name for that? Threshold MCS? Something else? "Threshold MCS" sounds ok to me, but I'm not great at naming things. -greg ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
