+# GitHub Actions workflow to test building pasls (server).
+#
+# To check
+# - whether it builds,
+# - whether the FPC and Lazarus versions in our
+#   Docker image are sufficient.
+#   (Right now, IdentComplIncludeKeywords requires Lazarus >= 3.0.0).
+#
+# This uses GitHub-hosted runners, that is: you don't need to set up any server
+# infrastructure, GitHub provides it all for free for open-source projects.
