Custom regions in Unix screen

My preferred Unix screen layout looks like this:

##########################
#                 #      #
#                 #      #
#                 ########
#                 #      #
#                 #      #
#                 ########
#                 #      #
#                 #      #
##########################


These are the .screenrc settings required:

# region 0 (width = max - 80; height = max)

screen -t 'LARGE LEFT REGION'

split -v

# region 1 (width = 80; height = max / 3)

focus

resize 80

screen -t 'RIGHT COLUMN: UPPER SCREEN'

# region 2 (width = 80; height = max / 3)

split

focus

screen -t 'RIGHT COLUMN: MIDDLE SCREEN'

# region 3 (width = 80; height = max / 3)

split

focus

screen -t 'RIGHT COLUMN: LOWER SCREEN'
