[R-sig-Debian] Difference between "depends on" and "import"

[denis brion]

 Hi
 I have noticed that, in some packages description, two fields are existing : "depends on" and "imports" . Where could I find the definition/difference between these two notions ?

This question seems rather stupid, but I have very restricted Internet access ("only" during week ends and holy-days) and a trustworthy IT link would be less misleading than google search and errors.

Thanks in advance.
