 %D Thus, the user should never supply any of these manually,
 %D neither before nor after \type{\typesetRSTfile}.

+%D We now handle rogue utf-8 byte order marks on demand, just set
+%D the optional parameter \type{stripBOM} to {\em true}.
+%D
+%D There also is an option \type{expandtab} to convert tabs
+%D (ascii 0x09) to indents prior to converting reST input. The
+%D expansion width defaults to {\em 4} and can be configured
+%D through the parameter \type{shiftwidth} (takes an integer).
