fakeroot to build a package?

[Eugene Zhukov <jevgeni.zh@gmail.com>]

Hello,

I came across this building tutorial [1]. It advertises using
fakeroot debian/rules binary
command to build a package. Needless to say it doesn't work for all packages.
I find this tutorial confusing. I know of two other IMHO better pages
on the topic [2] and [3].
Did I miss something or the first wiki needs fixing.?

[1] https://wiki.debian.org/BuildingTutorial
[2] https://wiki.debian.org/IntroDebianPackaging
[3] https://www.debian.org/doc/manuals/maint-guide/

Thanks,
Eugene
