[NTG-context] What would you call the core TeX-commands

If you had to name the core TeX-commands something, what would it be? Suggestions so far: initex: As initex is the command used to create TeX formats and only contains the core TeX-commands coretex: As they are the core TeX-commands The reason I ask is because I've written the new core-TeX-syntax-definition for Vim and I'd like to get the name right. Thanks. nikolai
