// FUNCTION OPENPOPUP
//
// This function's intention is to open a popup window containing a picture submitted
// by the variable POPURL, and display it at the appropriate size, submitted by the
// variables W (=width), and H (=height).
// The windows opened will appear without any control elements, which is intended.

// FUNCTION GETLASTMODIFIED
//
// This function delivers the date and time the document has been changed. This
// eliminates the need for lazy people like me to change it manually.
// Maybe minutes and seconds is too much... just remove them.

// his article "HTML Rechtschreibung" in c't 8/03.

// *any* other browser. The cool thing is that you can actually use it in your
// document header already to load the appropriate CSS file.
// Return values are: 'ie.css' and 'screen.css'
