Microsoft's True Type fonts can also be used on Linux. Not only can they improve visibility, they are essential for proper look and layout if you are using Internet Explorer on Linux for testing etc. The installation is very simple… well almost:
rpmbuild -bb msttcorefonts-2.0-1.spec
Note the path where the rpm is written and use it in the command below.
rpm -ivh /[path to rpm]/msttcorefonts-2.0-1.noarch.rpm
Restart the windows manager by pressing Ctrl-Alt-Backspace.
