Creating a master file for wise core 3 devices

[murderotica]

I don't really know where to post this thread but since my code in creating the firmware is in c, I'll try my luck here. I have an application that basically appends all files (u-boot, kernel, rootfs, etc.) into one bin file which forms my firmware file. I'm having a little trouble on how to create a master file (which is like a list of all the firmware files). This master file will be used for upgrading our device's firmware using the network (probably be used by the host web application for parsing? or checking? I'm not really sure). I can't find a resource in google or a tutorial on how to start creating the master file for wise core 3 devices. I will appreciate all the help I can get. Thank you :)
