1. When the downloaded data file from Mozilla is current, but the output
bundle does not exist: continue processing to create the bundle. The
goal is to have the output file - not just download the latest input.
2. added -f option to force re-processing the file. Useful for
debugging/testing the process.
3. added support for output to '-' (stdout), allowing the output to be
piped.
4. All progress and error messages go to STDERR rather than STDOUT (3)
5. The script opened and closed the output file many times
unnecessarily. It now opens it once, does the output and closes it.
6. Backup of the input files happens after successful processing, not
before.
7. The output is written to a temporary file, and renamed to the
requested name after backup - this greatly reduces the window where the
file can be seen partially written.
8. all die calls have a \n at the end to suppress perl's traceback - the
traceback isn't useful to end users.

Each certificate section of the input certdata.txt file has a trust
section following it with details.
This script failed to detect the start of the trust for at least one
cert[*], which made the script continue pass that section into the next
one where it found an 'untrusted' marker and as a result that certficate
was not included in the output.
[*] = "Hellenic Academic and Research Institutions RootCA 2011"

An alternative would be:
1. specify HTTPS_CA_DIR and/or HTTPS_CA_FILE
2. ensure that Net::SSL is being used, and IO::Socket::SSL is NOT being
used
This question and answer explain:

Only download and convert the certdata to the ca-bundle.crt if Mozilla
changed the data
The Perl LWP module (which in a bit of a circular reference is used by
mk-ca-bundle.pl) is now indirectly using this script. I made this small
tweak to make it easier to automatically maintain the generated
ca-bundle.crt file in version control.
The official Mozilla page at
http://www.mozilla.org/projects/security/certs/ points out a new place
as the "proper" place to get Mozilla's CA certs from so this script is
now updated to use that instead.
