#!/bin/sh
# Get only code blocks from rst file, use like:
# rst2code index.rst
# or
# cat index.rst | rst2code -
# pipe to bash if it is bash code e.g.
# rst2code index.rst | bash -x

                if (length(no_whitespace) == 0 && lines > 0) { code=0 }
                else { print no_edit; lines +=1; }
