+# Description:
+# 
+
+
+# This file converts the input stored in $(OPTIONS) variable into several different variables
+# depending in the content.
+#
+# $(OPTIONS) variable is assumed to contain following syntax:
+# -X,Y filename.ext -X filename.ext
+#
+# where X and Y are numbers for the color depth.
+# The first number is the actual color depth of the file and the second is the color depth
+# of the mask file. The second number (and the comma) may or may not be defined.
+#
+# Since there are color depths defined for both the actual file and it's mask file, we need
+# to determine also the name of the mask file somehow. 
+# It is assumed that depending on the mask file color depth (Y) 
+# the mask file has a different string appended to it's file name.
+#
+# These mask file strings must be defined in the variable $(MASK_OPTION_Y) where Y is the 
+# mask file color depth.
+#
+#
+# Options will be splitted into variables of $(FILES) which contains the filenames after the
+# options and to OPTION_$(FILE) where $(FILE) is each of the $(FILES) and 
+# $(OPTION1_$(FILE)) and $(OPTION2_$(FILE)) depending whether the option for the file
+# was infact 2 options separated with comma or not.
+# 
+# Example: lets consider following variables are defined:
+#
+# MASK_OPTION_1=_mask
+# MASK_OPTION_8=_mask_soft
+# 
+# And that our input is:
+# OPTIONS=-c8,1 calc_paper -c8,8 display_side_l -c8 display_center
+#
+# The option reader would go through the $(OPTIONS) and fill out following variables:
+#
+# FILES=calc_paper display_side_l display_center
+#
+#
+# OPTION_calc_paper=-c8,2
+# OPTION1_calc_paper=-c8
+# OPTION2_calc_paper=2
+# OPTION1_calc_paper_mask=-2
+#
+# OPTION_display_side_l=-c8,8
+# OPTION1_display_side_l=-c8
+# OPTION2_display_side_l=8
+# OPTION1_calc_paper_mask_soft=-8
+#
+# OPTION1_display_center=-c8
+

+#$(warning OPTION_LIST_WITHOUT_FILES $(OPTION_LIST_WITHOUT_FILES))

+)
+
+
+# If option consists of anything like *X,Y separate the parts from comma
+# The part before the comma is in OPTION1_file, if no comma it is same as OPTION_file
+# The possible part after the comma is in OPTION2_file
