Remarks
To use the ResettableFileTarget add a section element for nlog to the configSections element of app.config. Then add the Nlog configuration as a nlog element. The deleteToken attribute on the target element defines the token to look for in log messages to trigger resetting the log file. If not specified defaults to ~DELETE~LOG~FILE~.
