+# that it exists. Otherwise eqmake4 fails.
+#
+# All other arguments are appended unmodified to qmake command line.
+#
+# For recursive build systems, i.e. those based on the subdirs template,
+# you should run eqmake4 on the top-level project file only, unless you
+# have a valid reason to do otherwise. During the building, qmake will
+# be automatically re-invoked with the right arguments on every directory
+# specified inside the top-level project file.
