/**
 *  Fonts can be a pain in the ***.
 *  You can call them by name, but then you have to be very precise
 *  by writing their name in the script.
 *  An easier way is to call them by number
 *  but there you will face problems when you activate or deactivate fonts
 *  because their numbers will change.
 *
 *  This script writes a list of all available fonts
 *  on your system to the desktop.
 *  Have a look into new file.
 *  The weight is separated by a TAB.
 *  If you want to call a font by the name
 *  you have to write that TAB.
 *  Some IDEs translate the TAB character into four white spaces
 *  so be careful.
