Ipk: Supcam Enigma2

This tutorial shows how to build, package, and prepare a polished Enigma2 plugin package (.ipk) for a hypothetical video-streaming/stream-capture utility called "supcam". Assumptions: you have a Unix-like build host (Linux), basic cross-compilation toolchain for your target (commonly armv7 or mipsel for Enigma2 receivers), OpenEmbedded/Yocto or manual cross-compile setup, and familiarity with shell and Makefiles. I’ll assume target architecture armv7 (adjust triplets and toolchain names for other targets).
