Every parser is derived from senf::PacketParserBase. This class provides the necessary
housekeeping information and provides the parsers with access to the data.
+
+ \warning Parsers are like iterators: They are invalidated <em>whenever the size of the packet's
+ data is changed</em>. You should not store a parser anywhere. If you want to keep a parser
+ reference, use the senf::SafePacketParser wrapper. You still will need to take extra care to
+ ensure the parser is not invalidated.
