Options-List can be specified within a PKG file to display a list of options to the Symbian device user during installation. The options that are selected, control the installation of optional components.
!({"Option string language 1",...},...)
 For example,
!({"Add-on 1 (20KB)"},{"Add-on 2 (75KB)"},
  {"Add-on 3 (80KB)"},{"Add-on 4 (20KB)"}) 
 Each string corresponds to a PKG file variable called option1, option2 and
so on. The following are the values of these options: 
The selection affects the values of option attributes (option1,
option2, option3, ...). In the preceding example, if option1 (Add-on
1 (20KB)) is selected, then the value of the option1 attribute
changes from 0 to 1. 
You can test these values by specifying the optional components within conditional blocks as shown in the following example:
If option1 = 1
; install optional file 1 to the private directory
    "sample.txt"-"!:\private\E800005A\sample.txt";
endif
If option2 = 1
; install optional file 2 to the private directory
    "sample2.txt"-"!:\private\E800005A\sample2.txt";
endif  Note: The option<n> attributes behave
as global variables. 
The following example package file illustrates the usage of a basic options list.
;Languages

;Header
#{"Options"}, (0x81111107), 1, 2, 3,TYPE=SA
;Display 3 options to the user
!({"Install document (1KB)"},{"Install document2 (1KB)"},{"Install document3 (1KB)"})
if option1 = 1
    "files\option1.txt"-"!:\private\81111108\option1.txt";
endif
if option2 = 1
    "files\option2.txt"-"!:\private\81111108\option2.txt";
endif
if option3 = 1
    "files\option3.txt"-"!:\private\81111108\option3.txt";
endif The following example package file demonstrates an option list that supports multiple languages.
