UDP streams are written down in the usual fashion:
8 digit (hex) number 16 bytes in hex and double spaces between each 8 bytes ascii representation with nulls replaced with dots
00000000 00 00 00 00 00 00 00 00 ff ff ff ff ff ff ff ff ...(so on)
00000010 ...
Every analyzed part is notated with type...closing tag where ... represents an arbitrary amount of spaces, and both type and closing tag are 1-char to allow notating one byte in a way that takes the same amount of space.
The list of types is different for every file and is specified in the file.
The list of closing tags is the same for each each file:
. static
/ static but different for client->server and server->client packets
> changing with a rule
? dynamic (mostly used as unknown rule >)o
* static, specific to either client->server or server->client, depending on the indentation
