2# This ProGuard configuration file illustrates how to process a program
3# library, such that it remains usable as a library.
4# Usage:
5#     java -jar proguard.jar @library.pro

8# Specify the input jars, output jars, and library jars.
9# In this case, the input jar is the program library that we want to process.

16# Save the obfuscation mapping to a file, so we can de-obfuscate any stack
17# traces later on. Keep a fixed source file attribute and all line number
18# tables to get line numbers in the stack traces.
19# You can comment this out if you're not interested in stack traces.
