Framed minipages of a specified total width (text and frame combined)
Description
The package essentially just wraps a minipage within an \fbox.
However, while
\fbox{\begin{minipage}{\linewidth}...\end{minipage}} just out
into the margin, \begin{boxedminipage}...\end{boxedminipage}
does not. Instead, it subtracts the frame's dimensions from the
specified dimensions of the minipage before typesetting the
minipage.
