-# This Dockerfile compiles the jbig2enc library
-# Inputs:
-#    - QPDF_VERSION - the version of qpdf to build a .deb.
-#                     Must be present as a deb-src in bookworm
+#
+# Stage: pre-build
+# Purpose:
+#  - Installs common packages
+#  - Sets common environment variables related to dpkg
+#  - Aquires the qpdf source from bookwork
+# Useful Links:
