title: Can a Bash tab-completion script be used in zsh?
body: <p>I have a Bash tab-completion script for Apache's Hadoop.  Normally, I use zsh as my day-to-day shell.  It tends to be pretty bash-like when I need it to be, but it looks like the tab-completion systems are radically different between them.  Is there a simple way to "convert" the existing bash-tab-completion definitions to work in zsh?  I don't want to invest a ton of time in this, but if it's easy I'd save a moderate amount of effort.</p>
