# Turn on the serial port; if possible.  - means to ignore the error and keep
# going.  Without this, execution would halt here if this command failed (e.g.
# on Qube 2700; which lacks serial ports)

# Ask the user... which kernel?
# Timeout; 50/10 seconds
#
# The format is:
#   select "Message Goes Here" TimeOut label1 [label2 ... [labelN]]
#
# This will set the {menu-option} variable to the entry corresponding to the
# selected value, or 0 if no option is selected.

# Now... jump to the line corresponding to the selection...
#
# Explaination of the goto command...
#   goto [-]numMarks -- prefixing with - means jump backwards
# or
#   goto numMarks{b|f} -- b == jump back, f == jump forward
# 
# Marks are indicated by a line starting with a @ symbol.
# 
# We use this jump to set the {image-name} variable to a kernel image.

# Explaination of the var command:
#   var VariableName Value
