I assume you have not encountered SharePoint. The SharePoint documentation I could get my hands on - even in books I paid for - was so bad it was like I was living inside some David Lynch interpretation of Ancient Greek myths of divine punishments unleashed upon the worst sinners.
More than once, the "solution" to my problem was a blog post by a SharePoint consultant from India describing some undocumented flag to pass to some obscure command, "but of course, you should never do this on a production system". (I bear no ill will towards Indian SharePoint consultants, to be clear. I just find it really creepy they seem to enjoy this kind of torment.)
