Uzanto:TohaomgBot

This bot replaces all inclusions of some raster image with its analogue of format SVG, e.g. "some_image.jpg" with "some_image.svg". The pair of images is determined manually. The code of the program can be seen below (I allow anyone to use, share or change it, but not to get any financial profit from it). Bot is written on C# programming language using DotNetWikiBot library.
