16 imhistory ---- Retrieve and modify image history 

17 

18  

19 Retrieve and modify image history. 

20  

21 This task provides access to the logtable of an image, where generally 

22 history information is stored. Two operation modes are supported. When 

23 mode="list", the history messages are returned as an array of 

24 strings. If verbose=True, this information is also written to the 

25 logger. When mode="append", a specified message (along with its 

26 specified origin) are appended to the logtable and True is returned if 

27 successful.

35 mode Operating mode. 

36 Default: 'list' (retrieve history) 

37 Options: 'list|append' ('append' to append a
