+#    Instead of doing:
+#
+#[app]
+#source.exclude_patterns = license,data/audio/*.wav,data/images/original/*
+#
+#    This can be translated into:

+#[app:source.exclude_patterns]
+#license
+#data/audio/*.wav
+#data/images/original/*
+#
+
+
+#    -----------------------------------------------------------------------------
+#    Profiles
+#
+#    You can extend section / key with a profile
+#    For example, you want to deploy a demo version of your application without
+#    HD content. You could first change the title to add "(demo)" in the name
+#    and extend the excluded directories to remove the HD content.
+#
+#[app@demo]
+#title = My Application (demo)
+#
+#[app:source.exclude_patterns@demo]
+#images/hd/*
+#
+#    Then, invoke the command line with the "demo" profile:
+#
+#buildozer --profile demo android debug
