Could please add the old Microsoft WinHelp (.HLP) format as an input format for conversion? I see the current Microsoft Compiled HTML Help (.CHM) format is available as in input format.
I ask this because even though the old WinHelp format wasn't originally designed as an ebook format, it was used to create quite a number of ebooks which are now unreadable for the most part.
Your consideration and assistance in this matter is greatly appreciated.
