decresce and enddecresce

[neuro]

Another small question, on Lilypond 2.0.1 ...

I know about the
g4 \cresce g g \endcresce e2
. But how is the coresponding decrescendo things?
Lilypond doesn't know
g4 \decresce g g \enddecresce e2

I don't want the hairpins here.  I want the text "decresc. - - - " ; and it
automatically goes the right length of , say, 3 measures.


Thank you very much
