# generated correctly.  If a more generic .ps.pdf implicit target is defined,
# and cvs.ps is made before cvs.pdf, then cvs.pdf can be generated from the
# .ps.pdf target and the PS source, which contains less information (hyperlinks
# and such) than the usual texinfo source.
#
# It is possible that an implicit .ms.ps target could be safely defined.  I
# don't recall looking into it.
