27 From the documentation : 

28 

29 The annotation file (.ann) is a keyword/value ASCII file in which the value on the right of the equals sign 

30 corresponds to the keyword on the left of the equals sign. The number of keywords may change with time, so the line 

31 number should not be assumed to be constant for any given keyword. 

32 

33 In addition, the spacing between keywords and 

34 values may change. The units are given in parenthesis between the keyword and equal sign, and may change from 

35 annotation file to annotation file and within each annotation file. 

36 

37 Comments are indicated by semicolons (;), and 

38 may occur at the beginning of a line, or at the middle of a line (everything after the semicolon on that line is a 

39 comment). The length of each text line is variable, and ends with a carriage return. There may be lines with 

40 just a carriage return or spaces and a carriage return.
