PHP DocWriter?

that´s good just for backup. I mean pdf is hard to work with. to write in acrobat writer really sucks 🙂

you can edit pdf. but acrobat writer is no word processor.
but thanks for your hint anyway.

Here´s another cool solution…
I have recently build a website with the content manage system typo3. There´s a plugin called “General Office Displayer”.
You can import files to be shown online. Microsoft Office 2003 Word & Excel documents and Open Office Writer & Spreadsheet files are supported.

Now we can see there are possibilites to import “offline” files into a website and to export “web data” for offline usage.

Yes, it seems to be useful. You can write documentation. But there´s no possibilty to export in formats for offline usage.
