 \begin{classdesc}{ConfigParser}{\optional{defaults}}
 Return a new instance of the \class{ConfigParser} class.  When
 \var{defaults} is given, it is initialized into the dictionary of
-intrinsic defaults.  They keys must be strings, and the values must be 
+intrinsic defaults.  The keys must be strings, and the values must be 
 appropriate for the \samp{\%()s} string interpolation.  Note that
 \var{__name__} is an intrinsic default; its value is the section name,
 and will override any value provided in \var{defaults}.
