 +
 +      Move guimain.cpp out of the way.
 +
 +      * src/guimain.cpp: Rename file as...
 +      * src/guistub.cpp: ...this; we want to keep current features for now,
 +      but to use the guimain.cpp name for main GUI application development.
 +      * Makefile.in: Adjust references accordingly.
