pub const ABOUT: &str = "Git worktrees as daily-driver workspaces

workty makes Git worktrees feel like workspaces/tabs. Switch context without
stashing or WIP commits, see everything in flight with a dashboard, and clean
up merged work safely.";

pub const AFTER_HELP: &str = "EXAMPLES:
    git workty                    Show dashboard of all worktrees
    git workty new feat/login     Create new workspace for feat/login
    git workty go feat/login      Print path to feat/login worktree
    git workty pick               Fuzzy select a worktree (interactive)
    git workty rm feat/login      Remove the feat/login worktree
    git workty clean --merged     Remove all merged worktrees

SHELL INTEGRATION:
    Add to your shell config:
        eval \"$(git workty init zsh)\"

    This provides:
        wcd   - fuzzy select and cd to a worktree
        wnew  - create new worktree and cd into it
        wgo   - go to a worktree by name";
