+Scan rcynic validated output looking for router certificates, print
+out stuff that the rpki-rtr code cares about.
+"""
+
+# This program represents a weird temporary state, mostly to avoid
+# diving into a recursive yak shaving exercise.
+#
+# Under the old scheme, anything used by the RP code should be either
+# C code or pure Python code using just the standard libraries.  This
+# has gotten silly, but we haven't yet refactored the current packaged
+# builds from two packages into three (adding a -libs package).
+#
+# So, by rights, this program should be a C monstrosity written using
+# the OpenSSL C API.  I started coding it that way, but it was just
+# too painful for something we're probably going to rewrite as a few
+# lines of Python once we refactor, but by the same token I didn't
+# want to delay router certificate support until the refactoring.
+#
+# So this program anticipates the new scheme of things, but makes one
+# concession to current reality: if it has a problem importing the
+# RPKI-specific libraries, it just quietly exits as if everything were
+# fine and there simply are no router certificates to report.  This
+# isn't the right answer in the long run, but will suffice to avoid
+# further bald yaks.
