# drakfont Future Overview
#         - Fonts import:
#                 pfb ( Adobe Type 1 binary )
#                 pfa ( Adobe Type 1 ASCII )
#                 ttf ( True-Type  )
#                 pcf.gz
#                 Speedo
#                 and Bitmap (PCF, BDF, and SNF)
#         - Features
#                 - Install fonts from any directory
#                 - Get windows fonts on any vfat partitions
#                 - Get fonts on any partitions.
#                 - UN-installation of any fonts (even if not installed through drakfont)
#         - Support
#               - Xfs
#               - ghostscript & printer
#               - Staroffice & printer
#               - abiword
#		- netscape
#               - Koffice, Gnumeric, ... studying
#               - all fonts supported by printer
#               - anti-aliases by RENDER in Xfree86 .... 
# 				supported by KDE.
# 				will be supported by gnome 1.2.
# Visual Interface:
#         Window interface:
#           - Fontselectiondialog widget
#           - Command buttons under Fontselectiondialog (like the actual frontend).
#         Commands buttons:
#           - import from windows partition.
#                 import from all fat32 partitions and look for winnt/windows/font
#                 and import all (delete doubles) but do not import if they already exist.
#           - import from directory
#                 look to see if each font exists and do not delete the original.
#                 (replace all, no, none)
#                 expert options:
#                         specify the directory, and look to see if it exists before
#                         if it exists ask: (replace all, no, none)
#           - uninstall with list per font type
#         Expert additional switch
#           - option support:   ghostscript, Staroffice, etc...
#                 check-button. (by default all check)
#           - Printer Application Fonts Support...
#                 check-button. (by default all check)
