If you're seeing this text, then that means you're in the default trunk branch, where nothing of interest lives. This Fossil repository is split into multiple branches, one for each of my mods:

• WarZoneTweaks
• CreativeMenuTweaks
• Overpowerinator

If you're trying to install one or more of these mods manually by cloning the Fossil repo directly into your mod folder, that's easy to do by specifying a branch when opening:

cd $HOME/.avorion/mods  # or wherever your mods folder is
fossil clone https://fsl.yellowapple.us/avorion yamods.fossil
fossil open yamods.fossil WarZoneTweaks      --workdir WarZoneTweaks
fossil open yamods.fossil CreativeMenuTweaks --workdir CreativeMenuTweaks
fossil open yamods.fossil Overpowerinator    --workdir Overpowerinator

To create a branch for a new mod:

fossil open yamods.fossil --workdir MyNewMod
# ... make whatever changes ...
fossil ci --branch MyNewMod -m "some description"

(In the future this trunk branch will probably contain a "template" mod and other generically-applicable goodies, but I haven't gotten around to that yet.)
