and Syntax Highlighting for Kate Editor. Put bpf.xml file to C:\Users\username\AppData\Local\katepart5\syntax (~/.local/share/org.kde.syntax-highlighting/syntax on linux) and restart Kate if you have it launched. If you don't have this directory you can create it or launch update for syntax(Settings > Configure Kate > Open/Save > Modes & Filetypes > Download Highlighting Files) and it will create needed dir. It will be used by default for *.bpf files, but you can use it for *.txt files too. It can be on with Tools > Mode(Highlighting) > Other > Borderlands Patch File.
