[projektfu]

I'd include sed and awk, because these tools are ubiquitous and can accomplish in a few readable lines what people write long programs to handle in other languages, seemingly because they are unaware of sed and awk, don't know how to use them, or are required for some reason to do it in the project language.

In fact, generally teaching people to select the right tool for the job is a good skill to prevent them from using golden hammers.
