Welcome to the libplctag mailing list. Please use this as a forum to ask questions and share ideas.

This is a technical forum, not a commercial forum. While I do not mind the occasional job posting from members who are already contributing to technical discussions, this is not a place for recruiters.

Please keep it civil and calm and we'll all do fine.

The code and main site is at GitHub.
