   Ex: make DEBIAN_DATE=20070911t1711 nspr-orig
 
-   $ make client     (fetch and patch mozilla/client.mk from cvs)
+  You can fetch a specific branch by specifying DEBIAN_BRANCH.
+
+   Ex: make DEBIAN_BRANCH=MOZILLA_1_9a8_MINIBRANCH firefox-orig
+
+  It is also possible to use both DEBIAN_DATE and DEBIAN_BRANCH to fetch
+  the content of a branch at a particular date
+
+  Alternatively, you can fetch a specific CO tag using DEBIAN_TAG.
+  See 'make status' for a list of available tags.
+
+   Ex: make DEBIAN_TAG=MOZILLA_1_9a8_RELEASE firefox-orig
+
+  It is also possible to just call the new client.mk targets without
+  building tarballs:

    $ make -f mozilla/client.mk checkout MOZ_CO_PROJECT=nss
    $ make -f mozilla/client.mk checkout MOZ_CO_PROJECT=nspr
    $ make -f mozilla/client.mk checkout MOZ_CO_PROJECT=xulbrowser
