Sentry
======

Sentry is a realtime event logging and aggregation platform. It specializes
in monitoring errors and extracting all the information needed to do a proper
post-mortem without any of the hassle of the standard user feedback loop.

Sentry is a Server
------------------

The Sentry package, at its core, is just a simple server and web UI. It will
handle authentication clients (such as `Raven
<https://github.com/getsentry/raven-python>`_)
and all of the logic behind storage and aggregation.

That said, Sentry is not limited to Python. The primary implementation is in
Python, but it contains a full API for sending events from any language, in
any application.

        # command line flag for build_ext.  However as we are a subcommand
        # we need to grab this information from elsewhere.
        #
        # An in-place build puts the files generated into the source
        # folder, a regular build puts the files into the build-lib
        # folder.
        #
        # The following situations we need to cover:
        #
        #   command                         default in-place
        #   setup.py build_js               0
