<tutorial>
Find profiles example of using 51Degrees device detection. 
The example shows how to:
<ol>
<li>Use the DataSetBuilder to create a 51Degrees data set that will use a
custom caching configuration.
<p><pre class="prettyprint lang-cs">
string fileName = args[0];
DataSet dataSet = DataSetBuilder.File()                
                .ConfigureCachesFromTemplate(
                    DataSetBuilder.CacheTemplate.SingleThreadLowMemory)
                .SetCacheBuilder(CacheType.SignaturesCache, new CustomCacheBuilder())
                .SetCacheBuilder(CacheType.ProfilesCache, null)
                .SetTempFile(false)
                .Build(fileName)
</pre></p>
</ol>
This tutorial assumes you are building this from within the
51Degrees Visual Studio solution. Running the executable produced
inside Visual Studio will ensure all the command line arguments
are preset correctly. If you are running outside of Visual Studio,
make sure to add the path to a 51Degrees data file as an argument.
