• man ./lockf.1 renders the page properly

[bcr]

I'd use "will" instead of "shall".

How about "Success" instead of "Hello" ?

This one hurts.

I tend to do this before submitting: svn diff | aspell --lang=en list and then review the list. Clearly I didn't spot this one, but is there a better way of spell checking the changes?

Good to go now, thank you!

Maybe ispell? But I have my own internal spell checking, which is also not perfect and misses typos occasionally. Don't worry, that's why we have reviews where more eyeballs help catch these sort of things. ;-)
