+% The command \pictureunit[percent]{xsize}
+% selects the value of \unitlength so that the picture
+% which is xsize units in width occupies percent
+% width of the paper. By default percent=100 which
+% correspond to 90% of the total width of the paper.
+% \pictureunit calculates \unitlength corectly also for
+% twocolumn mode and inside itemize/enumerate/etc.
+%
+% Example:
+% \pictureunit{75}
+% \begin{picture}(120,80)
+% .....
+%
+% Default percentage value can be changed by
+% \renewcommand{\defaultpercent}{50}
+%
+% Environment mcpicture combines \pictureunit and
+% \begin{picture}-\end{picture}.
+%
+% \begin{Picture}(120,80)(-60,-40)
+% .......
+% \end{Picture}
+%
+% Optional parameter can contain percent width value
+% which is used instead of \defaultpercent:
+%
+% \begin{Picture}[50](120,80)(-60,-40)
