You could mark large sections of your files with:
#literal()
this ${text} will ${appear} as ${verbatim}
#end
to stop Velocity from interpolating the text at all.
alternatively you could use the following trick:
#set( $dollar = "$" )
an ${dollar}{example} variable
as afaik Velocity will only interpolate the text once.
