See mreadme.pdf for +%C details. + +%D This style is made in the process or writing the \METAFUN\ +%D manual. It exploits a few tricks, like graphics calculated +%D using positional information. It also uses the (at that +%D moment) new menu list placement alternative. If you forget +%D about the definition of the button shapes, which is +%D complicated in any system, this style is not even that hard +%D to follow. Watch how the left side of the buttons follow +%D the right side of the text graphic. +%D +%D While playing bit with this style, the random alternative +%D made me think of those organic building with non equal +%D windows (we have a few in The Netherlands), so I decided to +%D label this style as \type {pre-organic}. +%D +%D At the end of this file, there is a small test file, so +%D when you process this file with \TEXEXEC\ and the options +%D \type {--mode=demo} and \type {--pdf}, you will get a demo +%D document. + +%D We use one of the standard screen \quote {paper} sizes, and +%D map it onto the same size, so that we get a nicely cropped +%D page. + +\setuppapersize + [S6][S6] + +%D Like in the \METAFUN\ manual, we use the Palatino as main +%D bodyfont. This font is quite readable on even low +%D resolution screens, although I admit that this style is +%D developed using an $1400\times1050$ pixel LCD screen, so I +%D may be biased. + +%\startmode[asintended] \setupbodyfont[ppl] \stopmode + +%D The layout specification sets up a text area and a right +%D edge area where the menus will go.
