# in your repo's .git/hooks/ directory with golang fmt added at the bottom.
# An example hook script to verify what is about to be committed.
# Called by "git commit" with no arguments. The hook should
# exit with non-zero status after issuing an appropriate message if
# it wants to stop the commit.

This is a (hopefully) simple example of how to download your appengine logs to a normal

You can use appcfg.py to "request_logs" but that is not practical for real workloads
From here you can download smaller time slices of logs as necessary depending on your scale.
