+Optional dependency: qt4. If this is installed, the Qt4 support
+library for YafaRay (libyafarayqt.so) will be included in the
+package. To disable Qt4 support, export QT=no in the script's

 # 1.0 - Initial release.
 # 1.1 - Removed a bashism (==) to become ash-compatible.

+# 20220225 bkw: I just have to ask. Why care about being ash compatible?
+# When are you ever going to run this script with ash?
+
+# 20220222 bkw: Modified by SlackBuilds.org:
+# - fix bad github filename.
+# - do not install the docs with execute permission.
+# - reword README stuff about qt (it's not a "Qt GUI", it's a library)
+#   and mention qt4 as an optional dep.
+
+# Note: python bindings are not built, partly because it's hardcoded
+# for python 3.5, and (if overridden with YAF_PY_VERSION=3.9) because
+# it fails to build. Maybe someone will have time to fix this someday?
