+This is a quick shot at converting the MusE 1.0 sources to Qt4 using the
+Qt3Support compatibility classes. This far it looks quite promising the code
+compiles and is runnable. When used it is quickly found that things are not
+ok though. Hopefully we can fix most without too much effort
+
+-------
+The process this far has involved processing the codebase with the tool
+qt3to4 which substitutes many class types for their Qt3Support counterpart and
+adds the necessary includes (it missed quite a lot of includes though)
+
+Known issues:
+
+* One .ui file compiles to a nonfunctional .h file, mtrackinfobase.h, this far
+I have just commented the errenous line in the .h file (line 400 something)
+
+* Most things that I have touched that didn't feel 100% clear are marked with 
+'ddskrjo' so just grep the sources for ddskrjo to find potential issues and
+things that are outright commented out.
+
+* configuration of QT4 is hardcoded in configure.am, must be adapted with some 
+clever script there is also a hardcoded path to uic3 in common.am.
+We need both a way to detect this generically AND a way to use the correct uic
+for files that are converted to Qt4 format.
+
+* QTooltip has changed significantly so code that uses this is commented out.
+
+* When launched there are a bunch of errors printed, mostly QPainter that most
+likely point to actual problems. As I read in the migration docs previously it
+was supported to draw "on" a widget outside the paintEvent this isn't supported
+anymore (except with a specific define which we should probably steer clear of)
+
+* Can't open mixer
+* Can't open transport
+* Pianoroll is nonfunctional
+* Drumeditor is nonfunctional (hopefully the same problem)
