[Orgmode] [babel] options to the example directive

[Eric S Fraga]

I am finding org-babel incredibly useful in the preparation of
documentation for didactic purposes.  Kudos to the developers!  

I have two queries that I cannot seem to find an answer to in the
documentation: 

1. is there any way to specify arguments that should be generated for
   the #+begin_example line for the results of a babel invocation?
   Specifically, I would like to append automatically, for instance,
   arguments such as "-t -w 100 -h 20" so that the export to HTML
   output is presented in a text box that has scroll bars etc.

2. even if I manually put the options on the begin_example line, the
   export to HTML creates a '<pre class="example">' directive instead
   of what I would expect: '<textarea cols="40" rows="10">' or
   something similar.  I don't understand why exporting a file without
   babel constructs should behave differently from exporting with
   babel.  Should a begin_example section not export the same in both
   cases?

I am using org-mode and babel up to date as of this morning.

Any pointers highly welcome!

Thanks,
eric
