var appDescription = `tea is a productivity helper for Gitea.  It can be used to manage most entities on one
or multiple Gitea instances and provides local helpers like 'tea pull checkout'.
tea makes use of context provided by the repository in $PWD if available, but is still
usable independently of $PWD. Configuration is persisted in $XDG_CONFIG_HOME/tea.
