PowerShell
==========

The `Trace-Command` cmdlet can be used to enable tracing of certain PowerShell
subsystems. Use `Get-TraceSource` for a list of tracers:

* CmdletProviderClasses
* CommandDiscovery
* CommandSearch
* ConsoleHost
* ConsoleHostRunspaceInit
* ConsoleHostUserInterface
* ConsoleLineOutput
* DisplayDataQuery
* ETS
* FileSystemProvider
* FormatFileLoading
* FormatViewBinding
* LocationGlobber
* MemberResolution
* Modules
* MshSnapinLoadUnload
* ParameterBinderBase
* ParameterBinderController
* ParameterBinding
* PathResolution
* PSDriveInfo
* PSSnapInLoadUnload
* RunspaceInit
* SessionState
* TypeConversion
* TypeMatch

Then trace it like this:

```powershell
Trace-Command -Expression { Get-ChildItem . } -Name PathResolution -PSHost
```

The `-PSHost` specifies the sink, in this case the console host, so we can see
the tracing messages.
