[O] Configuring listings for file or language

[Jarmo Hurri]

Greetings.

The help documentation for the variable org-latex-listings-options
suggests that it is easy to configure these options
- globally for all files and languages using this variable
- for each code block separately using #+attr_latex

Is it possible to configure these options for all code blocks
1. in a single org file
2. for a single language?

Thanks!

Jarmo
