 LIMITATIONS
 -----------
 
-Several conditions controlling a person's significance are currently
-hard-coded, such as minimum participation level (10%), blame date-limiting (5
-years), and `-C` level for detecting moved and copied lines (a single `-C`). In
-the future, these conditions may become configurable.
