kind of double depency

[Sébastien BARTH ÉLEMY]

Hello,

I'm facing a makefile with following rule :

$(CFILES): %.scilab : %.sci
        $(SCITOC) $< >$(@)

I'd like to know what exactly means the a : b : c construction and
cannot find it in the "info make" pages nor on the web. It's probably
a keyword problem, I'm always falling back on double-colons (::)
explanations.

Any hint on what/where I should look for ?

Thanks a lot in advance.

best regards

(please, reply by mail directly)
