Explain what the Wuffs root directory is

[xobs]

The benchmark page seems to say that Wuffs benchmarks can be run by running "wuffs bench". However, this simply results in it saying that it can not find the Wuffs root directory. This happens even when running it from the repo where there is a directory called wuffs-root-directory.txt:

xobs@nas ~/C/wuffs> wuffs bench
could not find Wuffs root directory
xobs@nas ~/C/wuffs> ls -l
total 68

xobs@nas ~/C/wuffs> more wuffs-root-directory.txt
This placeholder file indicates the root of the Wuffs repository.

For example, filenames like "test/data/pi.txt" are relative to this root
directory.
xobs@nas ~/C/wuffs> wuffs bench
could not find Wuffs root directory
xobs@nas ~/C/wuffs>

Sorry about that.

What does go env and go version say for you?

I just installed go today by downloading it from https://golang.org/dl/, extracting it, and adding it to my PATH.

Might be fixed now. Please try again.

[xobs]

Yes, that does fix the issue. Thank you!
