Well... it's essentially easier than altering the modules to provide
them with a sheebang, making them executable and shipping
symlinks... whose targets wouldn't be the same in the v2 and v3
package...

Ah, thanks for spotting this... I thought it was a bit too easy indeed
;)

Hmmm... Maybe this is better :

  #!/bin/sh
  
  /usr/bin/python3 -c 'import rdflib.tools.csv2rdf' 2>/dev/null
  if [ "$?" = "0" ]
  then
      exec /usr/bin/python3 -m rdflib.tools.csv2rdf $*
  else
      exec /usr/bin/python -m rdflib.tools.csv2rdf $*
  fi

What do you think ?
