Please forgive this newbie's ignorance as I'm a complete neophyte when
it comes to SharePoint. Hopefully this isn't the quadrillionth time
this question is being asked but...

...as a technical writer, are there any content development/management
tools that will help me in producing content for SharePoint libraries?

My company is implementing SharePoint as a means of delivering
technical documentation and I was wondering if there are any tools that
integrate with SharePoint that also have traditional tech writing
functionality.

Any assistance or advice on this would be gratefully appreciated.
