Dockerfile.kerneldoc-alpine

FROM alpine:latest
# ARG variable example use:
# --build-arg ink=0 --build-arg img=1
#
# Defaults are:
#   ink=1 img=0
# librsvg is required by imagemagick-libs or ???
# Note:
#   xdvipdfmx can't handle translations.xdv on alpine:3.14 and later
#   For the moment, not having font-noto-cjk and skipping CJK chapters
#   looks like a reasonable compromise avoiding error in "make pdfdocs".
#   See Dockerfile.kerneldoc-alpine-glibc for a glibc based approach,
#   but be warned that it is only a happens-to-work thing.
