# This file controls GitLab CI (Continuous Integration) for FLTK.
#
# It serves two purposes:
#
# (1) Continuously building FLTK with one or more build systems.
# (2) Generating current HTML documentation and putting it online.
#
# The HTML documentation will be viewable at:
#
#   https://fltk.gitlab.io/fltk/
#
# The PDF documentation will be viewable at:
#
#   https://fltk.gitlab.io/fltk/fltk.pdf
#
# Details of this script:
#
# use the official gcc image, based on debian
# can use versions as well, like gcc:5.2
# see https://hub.docker.com/_/gcc/
