(show-help coll-path frame-title [verbatim?]) → (-> any) coll-path : (listof string?) frame-title : string? verbatim? : any/c = #f
Returns a thunk for showing a help window based on plain
text. Multiple invocations of the thunk bring the same window to the
foreground (until the user closes the window).
The help window displays "doc.txt" from the collection specified by coll-path.
The frame-title argument is used for the help window title.
If verbatim? is true, then "doc.txt" is displayed verbatim, otherwise it is formatted as follows:
Any line of the form **....** is omitted.
Any line that starts with * after whitespace is indented as a bullet point.
Any line that contains only -s and is as long as the previous line causes the previous line to be formatted as a title.
Other lines are paragraph-flowed to fit the window.
