QSciTE - a programmer's editor powered by Qt 4 and Scintilla
BUILDING qmake handles most of the heavy lifting. 'qmake qscite-debug.pro' or 'qmake qscite-release.pro' with a Qt 4 qmake and your favorite makespec will most likely do the right thing.
PLATFORM NOTES
Mac OS X The project file assumes that QScintilla has been installed as a framework. To do this, pass 'CONFIG += framework' to qmake when building QScintilla. The default OS X bundle is inadequate. After building, 'cp -R macx-bundle-contents/* QSciTE.app/Contents/' will update it.
