+# java_deobfuscate.py
+
+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 | build/android/stacktrace/java_deobfuscate.py out/Default/apks/ChromePublic.apk.mapping
+
+And have it actually show output without logcat terminating.
+
+
+## Update Instructions:
+
+ ninja -C out/Release java_deobfuscate
+ cp out/Release/lib.java/build/android/stacktrace/java_deobfuscate.jar build/android/stacktrace
+
+# stackwalker.py
+
+Extracts Breakpad microdumps from a log file and uses `stackwalker` to symbolize
+them.
+
+
+# crashpad_stackwalker.py
+
+Fetches Crashpad dumps from a given device, walks and symbolizes the stacks.
