[pkg-go] Bug#839108: dh-golang: Please document behavior and variables used

[Guillem Jover]

Package: dh-golang
Version: 1.19
Severity: wishlist

Hi!

I got to use this package, and when checking the man page realized
there was not much documented there. :)

Please document at least the variables from the environment that
directly affect the behavior such as GOPATH, DH_GOPKG,
DH_GOLANG_INSTALL_ALL, DH_GOLANG_INSTALL_EXTRA, DH_GOLANG_BUILDPKG,
DH_GOLANG_GO_GENERATE. And the field control field Go-Import-Path.

Listing other assumptions like source code layout or similar or
pointing to the relevant docs for more info would also be appreciated.

Thanks,
Guillem
