The list of packages is computed by finding all packages which end
up having either of PERL5_USE_PACKLIST, BUILDLINK_API_DEPENDS.perl,
or PERL5_PACKLIST defined in their make setup (tested via
"make show-vars VARNAMES=..."), minus the packages updated after
the perl package update.
sno@ was right after all, obache@ kindly asked and he@ led the
way. Thanks!
Most programming languages have a native Boolean data type. Perl
does not.
Perl has a simple and well known Truth System. The following scalar
values are false:
$false1 = undef;
$false2 = 0;
$false3 = 0.0;
$false4 = '';
$false5 = '0';
Every other scalar value is true.
This module provides basic Boolean support, by defining two special
objects: true and false.
