// Some information about Minipages in LaTeX:
// A minipage is a complete miniversion of a page and can contain
// its own footnotes, paragraphs, and array, tabular, and multicols
// environments. However it cannot contain floats or \marginpar's,
// but it can appear inside floats.
//
// The minipage environment is defined like this:
//
// \begin{minipage}[pos][height][inner-pos]{width} <text> \end{minipage}
//
// Where:
//     pos [opt] = is the vertical placement of the box with respect
//                 to the text baseline, [c], [t] and [b].
//     height [opt] = the height of the box
//     inner-pos [opt] =<3D>the position of the text within the box.
//                 It can be t, c, b or s, if unspecified the value
//                 of pos is used.
//     width = the width of the box
//
// In LyX we should try to support all these parameters, settable in a
// pop-up dialog.
// In this pop-up diallog it should also be possible to set all margin
// values that is usable in the minipage.
// With regard to different formats (like DocBook) I guess a minipage
// can be used there also. Perhaps not in the latex way, but we do not
// have to output "" for minipages.
// (Lgb)
