    18 # This file converts the input stored in $(OPTIONS) variable into several different variables

    19 # depending in the content.

    20 #

    21 # $(OPTIONS) variable is assumed to contain following syntax:

    22 # -X,Y filename.ext -X filename.ext

    23 #

    24 # where X and Y are numbers for the color depth.

    25 # The first number is the actual color depth of the file and the second is the color depth

    26 # of the mask file. The second number (and the comma) may or may not be defined.

    27 #

    28 # Since there are color depths defined for both the actual file and it's mask file, we need

    29 # to determine also the name of the mask file somehow. 

    30 # It is assumed that depending on the mask file color depth (Y) 

    31 # the mask file has a different string appended to it's file name.

    32 #

    33 # These mask file strings must be defined in the variable $(MASK_OPTION_Y) where Y is the 

    34 # mask file color depth.

    35 #

    36 #

    37 # Options will be splitted into variables of $(FILES) which contains the filenames after the

    38 # options and to OPTION_$(FILE) where $(FILE) is each of the $(FILES) and 

    39 # $(OPTION1_$(FILE)) and $(OPTION2_$(FILE)) depending whether the option for the file

    40 # was infact 2 options separated with comma or not.

    41 # 

    42 # Example: lets consider following variables are defined:

    43 #

    44 # MASK_OPTION_1=_mask

    45 # MASK_OPTION_8=_mask_soft

    46 # 

    47 # And that our input is:

    48 # OPTIONS=-c8,1 calc_paper -c8,8 display_side_l -c8 display_center

    49 #

    50 # The option reader would go through the $(OPTIONS) and fill out following variables:

    51 #

    52 # FILES=calc_paper display_side_l display_center

    53 #

    54 #

    55 # OPTION_calc_paper=-c8,2

    56 # OPTION1_calc_paper=-c8

    57 # OPTION2_calc_paper=2

    58 # OPTION1_calc_paper_mask=-2

    59 #

    60 # OPTION_display_side_l=-c8,8

    61 # OPTION1_display_side_l=-c8

    62 # OPTION2_display_side_l=8

    63 # OPTION1_calc_paper_mask_soft=-8

    64 #

    65 # OPTION1_display_center=-c8
