Description:
No problem. Just wondering if the documentation could be posted in PDF format so I could
download it and read it on my eReader.

UI language: en
Detected language: en

Comment 1:

does your eReader support chm, mobipocket or prc?
you could use wget to mirror the whole site and then bundle the resulting
local website as a chm/mobipocket or prc file for off line reading.

FYI, there is already issue #2381 for generating static docs.

Pretty much a dup of #2381 (x/tools/cmd/godoc: generate static docs), closing.
