# Description: Script to install Microsoft Vista TrueType Fonts (TTF) aka Microsoft’s ClearType fonts on Ubuntu distros
#              Microsoft added a group of new "ClearType Fonts" to Windows with Windows Vista and Office 2007.
#              These fonts are named Constantia, Corbel, Calibri, Cambria (and Cambria Math), Candara, and Consolas. 
#              Calibri became the default font on Microsoft Word 2007, and it’s still the default font on Word 2016 today.
# Dependencies: wget, fontforge and cabextract
# Note: Microsoft no longer provides the PowerPoint Viewer 2007 (v12.0.4518.1014) or any version anymore for download
# Tested: Ubuntu Saucy/Trusty/Xenial/Bionic
