25# This shell script creates a fresh ca-bundle.crt file for use with libcurl.
26# It extracts all ca certs it finds in the local Firefox database and converts
27# them all into PEM format.
28#
29# It uses the "certutil" command line tool from the NSS project to perform the
30# conversion. On Debian it comes in the "libnss3-tools" package.
