minted question

[Manfred Lotz <manfred.lotz@arcor.de>]

Hi there,
I have a an org file which gets exported to beamer. The following
example (although I do not know if there are errors) works fine.

Now I would like to get a frame around the perl code, and also line
numbers. How can I define this in the org file?

The following contains some perl code
- a minimal perl example
  #+BEGIN_SRC perl
  #! /usr/bin/perl
  
  use strict;
  use warnings;
  use 5.010;

  say 'hey';
  #+END_SRC
- the previous point shows the use of the minted environment
