[Gnumed-devel] --foo syntax meaning, conventions etc.

[J Busser]

the convention
        --talkback
was used in the related thread however
        --...

was also used in some of the discussion about gnumed configuration

I can't tell if the usage for such --items is related, whether it is 
part of a general Python convention or Python required method etc. 
What can I put over on the wiki* that people should understand 
"--foo" to be referring to, especially if it pertains to coding or 
module-writing guidelines?
