Wrong path in 2.4 "Meow!"

[lunaticabs]

Please quote the text that is incorrect:

echo "It works!" | ./build/bin/feline

In what way is this incorrect?

The path in here should be ./.lake/build/bin/feline. Because the current path should be in root directory in a project folder in general.

The book is currently targeting a version of Lean that's a couple of months old. But this will indeed need fixing the next time I update it to the current version (which needs doing soon, much has changed!).

Thanks!
