+/**
+This class manages a 16-bit resizable buffer and offers functions which can be used for constructing 
+SQL statements. 
+AppendL(), and AppendNumL() can be used to append data to the end of the buffer. 
+RLogDynBuf instance will try to expand the buffer if there is not enough available space for the data to be appended.
+
+The following code fragment shows how RLogDynBuf can be used:
+@code
+const TInt KGranularity = 128;
+RLogDynBuf buf;
+buf.CreateLC(KGranularity);
+buf.AppendL(_L("some data"));//AppendL() automatically expands the buffer if there is not enough place for the string
+buf.AppendNumL(1234);		 //AppendNumL() automatically expands the buffer if there is not enough place for the string
+buf.AppendL(_L("more data"));//AppendL() automatically expands the buffer if there is not enough place for the string
+......
+CleanupStack::PopAndDestroy(buf);
+@endcode
