The UIforETW repo now contains just five binary files and these are all
from Microsoft SDKs. They are all signed by Microsoft so they are "safe"
to have as binary files.

This should resolve issue #155.

UIforETW is a user interface for recording ETW (Event Tracing for
Windows) traces, which allow amazingly deep investigations of
performance problems on Windows. Its goals include:
 - making recording ETW traces easy for non-developers
 - making it easy to record additional contextual data such as user
input and CPU temperature in order to make trace analysis easier
 - making trace management easier for developers
 - working around bugs in WPT (Windows Performance Toolkit)

Tutorials on how to use ETW to investigate performance problems on
Windows can be found here:

UIforETW makes it much easier to control how traces are recorded than
using batch files or Microsoft's wprui. UIforETW also works around
numerous problems with ETW tracing (fixing symbol loading issues)
and adds extra features such as categorizing chrome processes,
monitoring working sets, etc.

UIforETW also lists all the recorded traces and displays editable notes
associated with each one.

UIforETW has some features that are specific to Chrome developers - but
it is fully functional for non-Chrome developers as well.

When adding TraceLogging and EventSource providers, UIforETW supports
the same *Name naming convention as other ETW tools. See
to ensure that your provider name and GUID conform to the convention.
EventSource providers should automatically match.
