[Ns-developers] random variable API-- current status

[Tom Henderson]

Below are the items that I believe still need to be implemented in 
ns-3-rng-changes:

>

> 7)  allow getting the global seed+run number from an env var. Suggested

>   --RngSeed=seed (seed is a single 32 bit number)
>   --RngRun=run
>

It seems to me that 6), 7), 8), 9) and 10) should be dealt with now, and 
11) may be dealt with later (there is bug 476 to track 11).  6) is 
related to 9).

In addition, there are some implementation questions and patches around 
that I haven't summarized above (the above focuses on API issues).

Other comments?
