# Preserve all annotations.

-keepattributes *Annotation*

# Preserve all public classes, and their public and protected fields and
# methods.

# Preserve all .class method names.

# classes.

# Explicitly preserve all serialization members. The Serializable interface

# You can comment this out if your library doesn't use serialization.
# If your code contains serializable classes that have to be backward
# compatible, please refer to the manual.
