[Cocci] How does the "when" statement work?

[Cocci] How does the "when" statement work?

[Timur Tabi]

I have a feeling that I can use the "when" statement for what I'm
trying to do in Coccinelle, but I can't figure out how it works.  I
can't find in the documentation where "when" is actually explained.
It appears that it's supposed to be documented here:

http://coccinelle.lip6.fr/docs/main_grammar005.html#when_code

but it isn't.

Would you like to tell a bit more about your next software transformation needs?

Can any information from previous discussions around SmPL code exclusion
specifications help here?

I hope also that the software documentation can be improved further together
with more development resources.
