+# This Perl script creates a fresh ca-bundle.crt file for use with libcurl.
+# It downloads certdata.txt from Mozilla's source tree (see URL below),
+# then parses certdata.txt and extracts CA Root Certificates into PEM format.
+# These are then processed with the OpenSSL commandline tool to produce the
+# final ca-bundle.crt file.
+# The script is based on the parse-certs script written by Roland Krikava.
+# This Perl script works on almost any platform since its only external
+# dependency is the OpenSSL commandline tool for optional text listing.
+# Hacked by Guenter Knauf.
