I think the major implication is not that it's simple but it's written
in some 'interpreted' (rather than compiled) language. so we say
Python or Perl or Bash script, but not 'C script'. Look at the job
openings: you'll often see something like this: 'knowledge of
scripting languages (such as Perl and/or Python)'.
