In a nut shell:
You open an input and output file.
You read a line in, if it is 'Node-path: calc' then you read another line
and if it is 'Node-action: add' then set a no_output flag.
You continue reading until you see 'whatever is end of block', clear
no_output flag and continue outputing whatever you read in.

Will the block always contain EXACTLY those four lines? Or can they
be somewhat different?
