+Subject: [PATCH] Make NM optional
+
+[ Alexandre Rostovtsev <tetromino@gentoo.org> :
+  * use config.js (and AC_SUBST HAVE_NETWORKMANAGER appropriately);
+  * take care to not import ui.status.network if nm is disabled;
+  * do not try to reassign to const variables;
+  * no point really in fiddling with the list of installed js files;
+  * don't build shell-mobile-providers if nm is disabled;
+  * use "networkmanager" instead of "network_manager" because THE
+    BIKESHED SHOULD BE BLUE, also because the upstream package name is
+    NetworkManager, not Network_Manager. ]
