-# 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.
