Carp::Clan - Report errors from perspective of caller of a "clan" of modules.

This module is based on "Carp.pm" from Perl 5.005_03. It has been modified to
skip all package names matching the pattern given in the "use" statement
inside the "qw()" term (or argument list).
Suppose you have a family of modules or classes named "Pack::A", "Pack::B" and
so on, and each of them uses "Carp::Clan qw(^Pack::);" (or at least the one in
which the error or warning gets raised).
Thus when for example your script "tool.pl" calls module "Pack::A", and module
"Pack::A" calls module "Pack::B", an exception raised in module "Pack::B" will
appear to have originated in "tool.pl" where "Pack::A" was called, and not in
"Pack::A" where "Pack::B" was called, as the unmodified "Carp.pm" would try to
make you believe :-).
This works similarly if "Pack::B" calls "Pack::C" where the exception is
raised, etcetera.
In other words, this blames all errors in the "Pack::*" modules on the user of
these modules, i.e., on you. ;-)
