errormsgs.R

### This file has two purposes:

# 1) to provide a check that these errors/warnings get a sensible context.
# 2) to allow translators to see their work in action.

### Initially it is concentrating on primitives.
### There are error messages that cannot nowadays be invoked or
### could only be invoked by calling .Internals directly.
