		"emNetwalk is a clone of the addictive Netwalk puzzle game where pieces of a\n"
		"computer network have to be rotated in order to connect terminals to a server.\n"
		"In contrast to other implementations, emNetwalk has a very sophisticated random\n"
		"network generator which allows a more free and exact game configuration. In\n"
		"addition, emNetwalk provides a special option for making the game even more fun:\n"
		"The Dig Mode forbids to rotate pieces that are not yet near a server connection.\n"
		"\n"
		"How to play\n"
		"-----------\n"
		"\n"
		"In order to solve the puzzle, you have to connect all the terminals to the\n"
		"server. You can do this by rotating pieces of the network (cable segments,\n"
		"junctions, terminals, and the server). The solution must not contain any loops\n"
		"or islands, so that there is always exactly one path from the server to each\n"
		"terminal. Every game has exactly one such solution.\n"
		"\n"
		"Mouse functions:\n"
		"\n"
		"  Left button: Rotate piece counterclockwise.\n"
		"\n"
		"  Shift + left button: Rotate piece clockwise.\n"
		"\n"
		"  Right button: Mark or unmark a piece. A marked piece cannot be rotated.\n"
		"\n"
		"  Ctrl + left button + movement: Scroll board (only in borderless mode)\n"
		"\n"
		"Here are some tips for beginners:\n"
		"\n"
		"4-way junctions are always correct and must not be rotated.\n"
		"\n"
		"A straight segment besides a border must point along the border.\n"
		"\n"
		"One or more straight segments between two terminals must not connect the\n"
		"terminals.\n"
		"\n"
		"An arc segment between two straight segments requires that the straight\n"
		"segments have different orientations."
