!
! The Options module automatically prefixes dummy_font with font_directory.
! The FontReader module then uses the font_directory and dummy_font values
! to decide on the location, format and naming convention of all font files.
! The above values assume you use PK files and keep them in one big directory.
! Note that the dummy_font file type has a font size equal to the resolution.
! If you are using Kellerman & Smith's old TeX system in which PXL files are
! kept in separate subdirectories then you'll need something like:
!
!    qualifier font_directory, nonnegatable,default,
!                                   value(default="tex_disk:[tex.fonts.]")
!    qualifier dummy_font,     nonnegatable,default,
!                                   value(default="[1500]cmr10.pxl")
!
! Note the important differences:
!    1. The font_directory value ends with ".]".
!    2. The dummy_font value ends with "PXL".
!    3. The font size is NOT in the file type; it is the subdirectory name.
!    4. The font size = resolution * 1000 / 200.
!
! PSDVI can handle any font scheme that obeys the following rules:
!  - The dummy_font value ends in either "PXL" or "PK" and all font files
!    use the same coding format.
!  - If the font_directory value ends in ".]" then all font files reside in
!    various subdirectories of font_directory.  Each subdirectory name is
!    a different font size and dummy_font must start with "[fontsize]".
!  - If the font_directory value does NOT end in ".]" then all font files
!    reside in font_directory.  Each file type begins with a font size and
!    dummy_font must start with "fontname.fontsize".
!  - The dummy_font value must represent an unmagnified font.  Its font size
!    substring matches either the resolution or (resolution * 1000 / 200).
!
! The above hackery is an attempt to cope with the various font schemes
! used by VAX/VMS TeX sites.  Note that GF files are not handled; I figured
! any sites using GF files would convert them to PK files sooner or later.
