~~~
(define-module (odoo odoo)
  #:use-module ((guix licenses)
                #:select (lgpl3))
  #:use-module ((guix licenses) #:select (lgpl3) #:prefix license:)

  #:use-module (gnu packages)
  #:use-module (gnu packages python)
  #:use-module (guix packages)
  #:use-module (guix download)
  #:use-module (guix utils)
  #:use-module (guix build-system python))

(define-public odoo
  (package
    (name "odoo")
    (version "9.0c")
    (source
     (origin
       (method url-fetch)
       (uri (string-append
"http://nightly.odoo.com/9.0/nightly/src/odoo_"; version
".20160610.tar.gz")) (sha256
        (base32
         "171gnax8syrz60iwi3k99di60x24z4f6c3s3wszb5xwgkir0ck7r"))))
    (build-system python-build-system)
    (native-inputs
     `(("python2-setuptools" ,python2-setuptools)))

    (arguments
     `(#:python ,python-2
       #:tests? #f))

    (home-page "http://www.odoo.com";)
