+#
+#  This module performs mathematical calculations:
+#
+#	Attribute-Name = "%{expr:2 + 3 + &NAS-Port}"
+#
+#  It supports the following operators (in order of precedence)
+#
+#	&	binary AND
+#	|	binary OR
+#	<<	left shift
+#	>>	right shift
+#	+	addition
+#	-	subtraction
+#	*	multiply
+#	/	divide
+#	%%	remainder
+#	^	exponentiation
+#	(...)	sub-expression
+#
+#  Operator precedence follows the normal rules.
+#  Division by zero means that the entire expression is invalid.
+#
+#  It also allows unary negation:	-1
+#  And twos complement:			~1
+#
+#  All calculations are done on signed 63-bit integers.
+#  e.g. int64_t.  This should be sufficient for all normal
+#  purposes.
+#
+#  Hex numbers are supported:		0xabcdef
+#
+#  As with all string expansions, you can nest the expansions:
+#
+#	%{expr: %{NAS-Port} + 1}
+#	%{expr: %{sql:SELECT ... } + 1}
+#
+#  Attribute references are supported for integer attributes.
+#  e.g. &NAS-Port.  The benefit of using attribute references
+#  is that the expression is calculated directly on the
+#  attribute.  It skips the step of "print to string, and then
+#  parse to number".  This means it's a little faster.
+#
+#  Otherwise, all numbers are decimal.
+#
+
+#
+#  The module also registers a few paircompare functions, and
+#  many string manipulation functions, including:
+#
+#  rand		get random number from 0 to n-1
+#		"%{rand:10}" == "9"
+#
+#  randstr	get random string built from character classes:
+#			c lowercase letters
+#			C uppercase letters
+#			n numbers
+#			a alphanumeric
+#			! punctuation
+#			. alphanumeric + punctuation
+#			s alphanumeric + "./"
+#			o characters suitable for OTP (easily confused removed)
+#			h binary data as lowercase hex
+#			H binary data as uppercase hex
+#
+#		"%{randstr:CCCC!!cccnnn}" == "IPFL>{saf874"
+#		"%{randstr:oooooooo}" == "rfVzyA4y"
+#		"%{randstr:hhhh}" == "68d60de3"
+#
+#  urlquote	quote special characters in URI
+#		"%{urlquote:http://example.org/}" == "http%3A%47%47example.org%47"
+#
+#  urlunquote	unquote URL special characters
+#		"%{urlunquote:http%%3A%%47%%47example.org%%47}" == "http://example.org/"
+#
+#  escape	escape string similar to rlm_sql safe_characters
+#		"%{escape:<img>foo.jpg</img>}" == "=60img=62foo.jpg=60/img=62" 
+#
+#  unescape	reverse of escape
+#		"%{unescape:=60img=62foo.jpg=60/img=62}" == "<img>foo.jpg</img>"
+#
+#  tolower	convert to lowercase
+#		"%{tolower:Bar}" == "bar"
