Configuration changes: $ENV{PSP_CONF} is now the
primary configuration key instead of
$ENV{PSP_TOP}; all $g_* global variables renamed
to $psp_*; default libperl directory is now
@prefix@/lib/perl5, and not @prefix/lib/perl.
Regression tests should now all work. Lots of
logic cleanups -- see various diffs for more
detail. Removed all dependencies on CPAN's
HTML::Parser. Added URI CPAN package. Please see
changelog for a full change list.
