+/* This file can be included to provide definitions of several things
+   many modules have in common.  It can be customized using the following
+   macros:
+
+     DEFINE_INIT	define the default initializer.  This requires the
+			following symbol to be defined.
+
+     CHARSET_NAME	string with official name of the coded character
+			set (in all-caps)
+
+     DEFINE_FINI	define the default destructor function.
+
+     MIN_NEEDED_FROM	minimal number of bytes needed for the from-charset.
+     MIN_NEEDED_TO	likewise for the to-charset.
+
+     MAX_NEEDED_FROM	maximal number of bytes needed for the from-charset.
+			This macro is optional, it defaults to MIN_NEEDED_FROM.
+     MAX_NEEDED_TO	likewise for the to-charset.
+
+     DEFINE_DIRECTION_OBJECTS
+			two objects will be defined to be used when the
+			`gconv' function must only distinguish two
+			directions.  This is implied by DEFINE_INIT.
+			If this macro is not defined the following
+			macro must be available.
+
+     FROM_DIRECTION	this macro is supposed to return a value != 0
+			if we convert from the current character set,
+			otherwise it return 0.
+
+     EMIT_SHIFT_TO_INIT	this symbol is optional.  If it is defined it
+			defines some code which writes out a sequence
+			of characters which bring the current state into
+			the initial state.
+
+     FROM_LOOP		name of the function implementing the conversion
+			from the current characters.
+     TO_LOOP		likewise for the other direction
+
+     RESET_STATE	in case of an error we must reset the state for
+			the rerun so this macro must be defined for
+			stateful encodings.  It takes an argument which
+			is nonzero when saving.
+
+     RESET_INPUT_BUFFER	If the input character sets allow this the macro
+			can be defined to reset the input buffer pointers
+			to cover only those characters up to the error.
+
+     FUNCTION_NAME	if not set the conversion function is named `gconv'.
