Abstract: The invention relates to a method for modifying a source code, wherein potential modification locations of the source code to be modified are pre-defined by means of comment markers already placed in the source code to be modified, and clearly referenced, whereby the source code to be modified is first read out by means of a parser, and the comment markers contained in the source code are recognized, whereby an input panel is generated for every comment marker, on the basis of the data contained in the comment markers, in each instance, whereby the required data for individual adaptation of the software are queried from the user, checked and, if necessary, corrected, by way of this input panel, and the modifications are entered into the source code to be modified, on the basis of these defaults as well as the sets of rules contained in the comment markers.
