 """
 A class representing a Type 1 font.
 
-This version merely allows reading in pfa and pfb files, stores the
-data in pfa format, and allows reading the parts of the data in a
-format suitable for embedding in pdf files. A more complete class
-might support subsetting.
+This version merely reads pfa and pfb files and splits them for
+embedding in pdf files. There is no support yet for subsetting or
+anything like that.
 
-Usage:  font = Type1Font(filename)
-        somefile.write(font.data) # writes out font in pfa format
-        len1, len2, len3 = font.lengths() # needed for pdf embedding
+Usage (subject to change):
+
+   font = Type1Font(filename)
+   clear_part, encrypted_part, finale = font.parts
