I'm not sure --''-- is an internationally recognized way of saying 'ditto'.
Replace by "same as --generate-app-cache"
Why is this even here? Can you write "false" too? 

[Johnni Winther, 2012/07/09 14:57:18]

You can't write --generate-app-cache=false. I think we should just remove the
documentation for --generate-app-cache=true but leave the implementation in case
anyone should still rely on it. The '=true' option syntax seems to be inherited
from apidoc.

[Lasse Reichstein Nielsen, 2012/07/09 10:39:33]

I never like ignoring an exception.
So you first check if it exists, then deletes it and then recreates it. Sounds
race-condition prone if ever run simultaneously with anything that uses the same
directory, or, heavens forbid, itself.
How about renaming the directory to a temporary name first, then create the new
one, and then delete the old one (asynchroneously). If that deletion fails
(e.g., because someone had a shell open in a subdirectory), it's not a problem
for this process. It can just print a reminder: "Unable to delete directory
blahblah.tmp-11257897125, please remove it manually."
