+This folder is a subpackage of ttLib. Each module here is a 
+specialized TT/OT table converter: they can convert raw data 
+to Python objects and vice versa. Usually you don't need to 
+use the modules directly: they are imported and used 
+automatically when needed by ttLib.
+
+If you are writing you own table converter the following is 
+important.
+
+The modules here have pretty strange names: this is due to the 
+fact that we need to map TT table tags (which are case sensitive) 
+to filenames (which on Mac and Win aren't case sensitive) as well 
+as to Python identifiers. The latter means it can only contain 
+[A-Za-z0-9_] and cannot start with a number. 
+
+ttLib provides functions to expand a tag into the format used here:
+
+>>> from fontTools import ttLib
+>>> ttLib.tagToIdentifier("FOO ")
+'F_O_O_'
+>>> ttLib.tagToIdentifier("cvt ")
+'_c_v_t'
+>>> ttLib.tagToIdentifier("OS/2")
+'O_S_2f_2'
+>>> ttLib.tagToIdentifier("glyf")
+'_g_l_y_f'
+>>> 
+
+And vice versa:
+
+>>> ttLib.identifierToTag("F_O_O_")
+'FOO '
+>>> ttLib.identifierToTag("_c_v_t")
+'cvt '
+>>> ttLib.identifierToTag("O_S_2f_2")
+'OS/2'
+>>> ttLib.identifierToTag("_g_l_y_f")
+'glyf'
+>>> 
+
+Eg. the 'glyf' table converter lives in a Python file called:
+
+	_g_l_y_f.py
+
+The converter itself is a class, named "table_" + expandedtag. Eg:
+
+	class table__g_l_y_f:
+		etc.
+
+Note that if you _do_ need to use such modules or classes manually, 
+there are two convenient API functions that let you find them by tag:
+
+>>> ttLib.getTableModule('glyf')
+<module 'ttLib.tables._g_l_y_f'>
+>>> ttLib.getTableClass('glyf')
+<class ttLib.tables._g_l_y_f.table__g_l_y_f at 645f400>
+>>> 
+
+You must subclass from DefaultTable.DefaultTable. It provides some default
+behavior, as well as a constructor method (__init__) that you don't need to 
+override.
+
+Your converter should minimally provide two methods:
+
+class table_F_O_O_(DefaultTable.DefaultTable): # converter for table 'FOO '
+	
+	def decompile(self, data, ttFont):
+		# 'data' is the raw table data. Unpack it into a
+		# Python data structure.
+		# 'ttFont' is a ttLib.TTfile instance, enabling you to
+		# refer to other tables. Do ***not*** keep a reference to
+		# it: it will cause a circular reference (ttFont saves 
+		# a reference to us), and that means we'll be leaking 
+		# memory. If you need to use it in other methods, just 
+		# pass it around as a method argument.
+	
+	def compile(self, ttFont):
+		# Return the raw data, as converted from the Python
+		# data structure. 
+		# Again, 'ttFont' is there so you can access other tables.
+		# Same warning applies.
+
+If you want to support TTX import/export as well, you need to provide two
+additional methods:
+
+	def toXML(self, writer, ttFont):
+		# XXX
+	
+	def fromXML(self, (name, attrs, content), ttFont):
+		# XXX
+
