Try using MacPerl::Ask() with perl 5.
For online man pages (pod pages really) use the Shuck application
that comes with MacPerl. Note that under Shuck's helpful
pull down menu all the pod pages have been
re-titled to single descriptive words like "Functions"
that do not map directly into the pod page name. You want the
Mac Specfic features document.
