+# When using the "either" method, ranger determines which program to
+# pick by looking at its dependencies.  You can set dependencies by
+# adding the decorator "depends_on":
+#     @depends_on("vim")
+#     def app_vim(self, context):

+# There is a special keyword which you can use as a dependence: "X"
