Done.

MakeDirIfNotExists?  the current name sounds assert-y... but maybe that's just
me.

[cjhopman, 2013/03/15 22:44:39]

Yeah, I didn't really like this name either... Maybe MkDirDashP? That's what
this is really doing...

How about just MakeDirectory.

Why would we have these charcters in strings? "$" for inner classes? Double
quote?

[cjhopman, 2013/03/15 22:44:39]

Precisely. I could find no way to escape/quote such a string to make it work.

[newt (away), 2013/03/15 03:25:04]

is there any way we can change the generator to support $?  it would be nice to
have this escaping built into gyp.

[cjhopman, 2013/03/15 22:44:39]

I agree. Updated with a gyp bug tracking this.
