#
# build() ends on a po4a call that renders the man page into every language it
# has a catalogue for. po4a is Perl, and packaging it means packaging its module
# stack -- perl-yaml-tiny, perl-syntax-keyword-try, perl-term-readkey,
# perl-locale-gettext and more -- so that fakeroot's man page exists in Polish.
#
# fakeroot is not optional the way its man pages are: makepkg cannot build a
# package without it. Same arbitration as --auto-features auto in
# build-stage2.sh, and the same note for stage 3.
