21 class for reading and mapping a file.
23 duplicates a lot of Data_file and Text_stream.
24 should look at including Data_file's functionality:
25 get_line (), get_word () here.

39 bool contains (char const* pos_str0 ) const;
41 virtual int get_line (char const* pos_str0 ) const;
42 String name_string () const;
43 String file_line_column_string (char const* str0 ) const;
46 char const* seek_str0 (int n);
49 // return here + n bytes

63 This thing doubles as a file-storage/file-iterator object.
