+The best match for I<name> is font I<font>. A perfect match has a
+I<number> of 0.00000. Worse matches observe larger values. If a tie
+is reported, this means one or more fonts matched I<name> equally well
+(i.e., they see the same I<number>). In this case, B<pkfix-helper>
+selects the qualitatively most likely font as the winner.

+B<dvips>-produced PostScript files can be structured in sections,

+names are local to a section. Hence, a font named C<Fa> may map to

+assigns every font in a multi-section document a unique name by

+Font names are processed in decreasing order of the number of

+C<Fb>, B<pkfix-helper> will process C<Fb> before C<Fa>.
