Framed or shaded regions that can break across pages
Description
The package creates three environments: framed, which puts an
ordinary frame box around the region, shaded, which shades the
region, and leftbar, which places a line at the left side. The
environments allow a break at their start (the \FrameCommand
enables creation of a title that is "attached" to the
environment); breaks are also allowed in the course of the
framed/shaded matter. There is also a command \MakeFramed to
make your own framed-style environments.
