>>>I would like to have a macro similar to \fbox, but with rounded corners.

Apparently there is some interest, judging from the mail I got.
So here is the latest-and-greatest version. There are two improvements:
- Previously, \ovalfbox generated overfull \hboxes. This is now fixed.
- When a \parbox or \minipage, or something else which is big, is put in
  a \ovalfbox, things inside stick beyond the frame, which is extremely
  ugly. To solve this, there is an extra \Ovalfbox macro. (Thanks to
  Mauro Orlandini.)

The macros should be put in a style file. Since some questions I got
were related to this, I have included a ready-for-use style file here.
