Since initially running `package.skeleton` to create a package, I have added several S3 classes. Each of these classes has 5-10 methods. I've discovered the wonderful `prompt` command to create .Rd files from a function loaded into memory, but is it possible to have R automagically create a single help file that has all multiple functions documented? I'm thinking of something like an enhanced version of `prompt` where you would pass it a list of functions, and it would create a single .Rd file with only the additional information added to the help file.

For instance, if I have a generic called `duration`, and classes for which there are methods `duration.bond(market,...)`, `duration.account(market,time,...)`, `duration.portfolio(market,...)`, I would like `prompt` to create a helpfile with a `\usage` section containing each `\method{}` and an `\arguments{}` section containing `market`,`\dots`, **and** `time`.

Any hope here? Copying and pasting is getting very tiring!
