The dejagnu-1.4.4/README says that there is a 'make overview.html' target,
but gmake complains that there isn't. Not in the main directory. The
Makefile in the doc directory seems to have the target: After a 'cd doc'
it tries (but fails for the same reason as overview.ps below):
Also, 'make overview.ps' doesn't work
ksh: /db2dvi: not found
(maybe I should have db2dvi or something installed somewhere in a path...)
