Hi Kaushal and Jeremie,

Thanks for the comments.  And sorry for the misleading example.  I do not
want to use source blocks to insert a date.  In fact I want to include
the current git commit hash on the title slide.

So, something like this:

src_sh[:exports results :results output wrap replace]{git describe --always 

But that is not evaluated...

Any hint?
