Hello all, Prompted by a question on c.t.t., I've done a sweep over all of TeX Live and added all of the expl3 prefixes which are in use to the database I mentioned some time ago. As this has been done in a somewhat automated manner, package authors are advised to check the results (https://github.com/latex3/svn-mirror/blob/master/l3kernel/l3prefixes.csv). I'd also like to strongly encourage developers to register their prefixes by submitting them either directly to the team, to me or to sending them to the list. I'll try to pick up new uses as they pop up on the CTAN list, but may not catch everything. -- Joseph Wright
