+# This file controls GitLab CI (Continuous Integration) for FLTK.
+#
+# It serves two purposes:
+#
+# (1) Continuously building FLTK with several build systems.
+# (2) Generating current HTML documentation and putting it online.

+# The documentation will be at:

+# https://fltk.gitlab.io/fltk/
+#
+# Details of this script:
+#
+# use the official gcc image, based on debian
+# can use versions as well, like gcc:5.2
