Well I was reading sources and stumbled over these commands. I am using 
shortcuts to typeset programming examples in non standard languages and 
pseudo-code.

Many thanks! I've looked this indeed!

It is a pity that such useful command (setups) remains undocumented. As 
far as I understand inside setups can be any commands and environment 
changes are fully restored after their execution. Right? And \setups 
command can replace any single command (in arguments and such).

If this is OK, then I will try to collect some more examples and post 
them on the WIKI later this week.
