A wrapper around ProGuard's ReTrace tool, which:

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

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

And have it actually show output without logcat terminating.

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