Is there any interest in a method of taking a package with
documentation in Rd files and attaching it to package R files in
Roxygen format? I can see a few problems with a totally general
solution but it might be possible to make a script that provides a
kickstart to converting a package to Roxygen

A lot of R packages are now effectively maintained by several people

means the best way to report bugs or problems with these packages is

Currently when R starts up it can be configured by a file of

programmatic modification of startup configuration tricky.

Is there a good reason why arguments to 'attach' and 'detach' differ so
much? Yes, I know this is the documented behaviour, it just seems to
