 Keep your repo fresh with one command.
 
-* Stashes your unstaged changes
-* Updates local master to match remote, prunes stale branches
-* Deletes stale local and remote branches with `-f` flag
-* Merges remote master into current branch with `-m` flag
-* Rebases current branch against remote master with `-r` flag
-* Restores your stashed changes with `-s` flag
-* Wipes the slate clean with `-F` flag
