# This Perl script creates a fresh ca-bundle.crt file for use with libcurl.
24+
# It downloads certdata.txt from Mozilla's source tree (see URL below),
25+
# then parses certdata.txt and extracts CA Root Certificates into PEM format.
26+
# These are then processed with the OpenSSL commandline tool to produce the
27+
# final ca-bundle.crt file.
28+
# The script is based on the parse-certs script written by Roland Krikava.
29+
# This Perl script works on almost any platform since its only external
30+
# dependency is the OpenSSL commandline tool for optional text listing.
31+
# Hacked by Guenter Knauf.
