Escapng problem

Hi

I have a problem with escaping '$' character in Velocity

I want to produce literal:
arg1value="${var:maxlength}"

When i type it in my template "as is" I recive an exception:

     [java] org.apache.velocity.exception.ParseErrorException: 
Encountered ":maxlength}\"\r\n" at line 25, column 49.
     [java] Was expecting one of:
     [java] "}" ...
     [java] <DOT> ...


When I type

arg1value="\${var:maxlength}"

result is the same.

Thanks for response

I tried :

#set( $d = '$' )
arg1value="$d{var:maxlength}"

but result is still 


 [java] org.apache.velocity.exception.ParseErrorException:
Encountered ":maxlength}\"\r\n" at line 25, column 49.
     [java] Was expecting one of:
     [java] "}" ...
     [java] <DOT> ...

#set( $d = '$' )
arg1value="$d{var:maxlength}"

or if you have the EscapeTool in the context (from VelocityTools)

arg1value="$esc.d{var:maxlength}"

\$foo is for escaping _references_ not for escaping the $ character. 
velocity was still trying to parse it as a reference.
