+# Based on Enrico's snippet for using pdflatex for building PDFs, except we're
+# switching to pregenerating the docs for the SRPM so that we don't get
+# different contents when we build on multiple build machines and architectures
+# (timestamps and IDs change, and even some of the compressed content looks
+# different).  The filename and checksum are used to verify that the PDF always
+# matches the doc which was used to generate it, and we flag an error if that
+# isn't the case.
