I'm confused about the documentation tag. Its tag wiki excerpt states:
You should tag questions as {documentation} when they address issues related to the writing of documenting TeX packages, or to packages designed for documenting TeX code, e.g., ltxdoc.
So, as I understand this, the tag is about how to write documentation (e.g., about dtx files).
On the other hand, most of the questions tagged documentation are actually about finding documentation. Further, manual is a synonym of documentation.
What is the correct use? Should we split the tag into two?
(Compare also books, tutorials and Tags about documentation.)
[Sorry for this shameless way to move this question up, but I was just about to ask the same thing, and I cannot offer a bounty on meta (which I would gladly do if I could). tohecz]
