+@cindex fonts, searching
+
+Basically, there is no restriction how font files for @code{groff} are
+named and how long font names are; however, to make the font family
+mechanism work (@pxref{Font Families}), fonts within a family should
+start with the family name, followed by the shape.  For example, the
+Times family uses @samp{T} for the family name and @samp{R}, @samp{B},
+@samp{I}, and @samp{BI} to indicate the shapes `roman', `bold',
+`italic', and `bold italic', respectively.  Thus the final font names
+are @samp{TR}, @samp{TB}, @samp{TI}, and @samp{TBI}.
+
+@cindex font path
+@cindex path, for font files
+All font files are kept in the @dfn{font directories} which constitute
+the @dfn{font path}.  The file search functions will always append the
+directory @code{dev}@var{name}, where @var{name} is the name of the
+output device.  Assuming, say, DVI output, and @file{/foo/bar} as a
+font directory, the font files for @code{grodvi} must be in
+@file{/foo/bar/devdvi}.
+
+The elements of the search path for font files are (in that order):
+
+@itemize @bullet
+@item
+The directories specified with @code{gtroff}'s or @code{groff}'s
+@option{-F} command line option.  All device drivers and some
+preprocessors also have this option.
