To update smlib: We will merge the latest smlib/feature-pluginmanager into addons/sourcemod. Commit messages are squashed, that means the history of feature-pluginmanager is compressed to one commit.

git remote add smlib git@github.com:bcserv/smlib.git
// fetch the latest changes to the target branch
git fetch smlib feature-pluginmanager
// folder addons/sourcemod must exist!
git merge --squash -srecursive -Xsubtree=addons/sourcemod --strategy-option theirs  smlib/feature-pluginmanager
