java_deobfuscate

A wrapper around ProGuard's ReTrace tool, which:

1. Updates the regular expression used to identify stack lines, and
2. Streams its output.

The second point here is what allows you to run:

adb logcat | out/Default/bin/java_deobfuscate out/Default/apks/ChromePublic.apk.mapping

And have it actually show output without logcat terminating.

stackwalker.py

Extracts Breakpad microdumps from a log file and uses stackwalker to symbolize them.
