#######################################################
#
# Main options file for LinuxBIOS
#
# Each option used by a part must be defined in
# this file. The format for options is:
#
#   define <name> 
#	default <expr> | {<expr>} | "<string>" | none
#	format "<string>"
#	export always | used | never
#	comment "<string>"
#   end
#
# where 
#
#   <name> is the name of the option
#   <expr> is a numeric expression
#   <string> is a string
#
# Either a default value or 'default none' must
# be specified for every option. An option
# specified as 'default none' will not be exported
# (i.e. will remain undefined) unless it has
# been assigned a value.
#
# Option values can be an immediate expression that 
# evaluates to a numeric value, a delayed expression 
# (surrounded by curley braces), or a string 
# (surrounded by double quotes.)
#
# Immediate expressions are evaluated at the time an
# option is defined or set and the numeric result 
# becomes the value of the option.
#
# Delayed expression are evaluated at the time the 
# option is used, either in another expression or 
# when being exported.
#
# String values will have the double quotes removed 
# automatically. 
#
# Format strings determine the print format that is 
# used when exporting options. The default format
# is "%s" for strings and "%d" for numbers.
#
# Exported options generate entries in the 
# Makefile.settings file. Options can be always 
# exported, exported only if used, or never exported.
#
# A comment string must be supplied for every option.
