 - **getDebianAnnouncements.py** By https://github.com/rpasche This downloads all security announcements of debian from the current year and the year before and uses html2text to transform it to ascii text
 - **parseUbuntu.py** parses https://lists.ubuntu.com/archives/ubuntu-security-announce/$DATE.txt.gz into an XML which can be read by errata-import.pl / errata-import.py
 - **parseDebian.py** By https://github.com/rpasche the same as parseUbuntu.py, but parses all security announcements downloaded with getDebianAnnouncements.py and writes this to an XML file for later use with errata-import-debian.py
