Hi everyone,

I think an interesting feature in R would be "package list dump" option.
The way I see this working is the following: the user would issue
a command on the source R installation (say, an older version), e.g.
Then the user would run the destination installation (say, a new version)
and recreate the environment by issuing a command like:
This last command would go and download and install all packages that
were listed in the dump.

Or maybe this is already possible?
