+#
+# 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.
