Hg checkout missing config and friends

[Jeffrey Walton]

I performed a checkout to the latest stable:

  $ hg clone http://hg.nginx.org/nginx -u "release-1.4.4"

I tried to run config, and it appears to be missing:

  $ ./config
  -bash: ./config: No such file or directory
  $ nginx-release-1.4.4$ ls
  auto    conf    contrib    docs    misc    src

The file is present in the tarball on the website.

How does one get all the files for release-1.4.4?

(Forgive me if I only need to copy the one file. Its not readily
apparent to me what I should do at this point).

Thanks in advance.
