The transform commands are:
-*: =SET <attr> <expr>= Set =<attr>= to =<expr>=
-*: =EVALSET <attr> <expr>= Evaluate =<expr>= and then set =<attr>= to the result
-*: =DEFAULT <attr> <expr>= Set =<attr>= to =<expr>= if =<attr>= is undefined or missing
-*: =COPY <attr> <newattr>= Copy the value of =<attr>= to =<newattr>=
-*: =COPY /<regex>/ <newattrs>= Copy the values of attributes whose names match =<regex>= to =<newattrs>=.
-*: =RENAME <attr> <newattr>= Rename =<attr>= to =<newattr>=
-*: =RENAME /<regex>/ <newattrs>= Rename attributes matching =<regex>= to =<newattrs>=
-*: =DELETE <attr> <newattr>= Delete =<attr>=
-*: =DELETE /<regex>/= Delete attributes matching =<regex>=
-*: =EVALMACRO <key> <expr>= Evaluate =<expr>= and then insert it as a transform macro value
-*: =TRANSFORM [<N>] [<vars>] [in <list> | from <file> | matching <pattern>]= Do the Tranform

-In the above commands =<attr>= must be a valid attribute name and =<expr>= a valid ClassAd
+Optionally, a transform rule set can end with an iteration command
+
+=TRANSFORM [<N>] [<vars>] [in <list> {quote:|} from <file> {quote:|} matching <pattern>]=
+
+In the above commands =<attr>= must be a valid attribute name and =<expr>= a valid {quote: ClassAd}
expression or literal. The various $() macros will be expanded in =<expr>=, =<newattr>= or
=<newattrs>= before they are parsed as {quote: ClassAd} expressions or attribute names.
