+form logical fonts used in (u)pTeX.  The functions currently available
+include:
+@itemize
+@item The mutual conversion between Japanese virtual fonts (pairs of VF and
+JFM) and files in the ZVP format, which is an original text format
+representing data in virtual fonts.  This function can be seen as
+a counterpart to the @code{vftovp} and @code{vptovf} programs.
+@item The mutual conversion between VF files alone and files in the ZVP0
+format, which is a subset of the ZVP format.
