##
## Some functionality of Unicode-Map-0.105 is deprecated now. It is either
## removed from the documentation or explicitly marked deprecated there.
##
## Anyway old code applying Unicode::Map should remain intact. This test
## asserts that:
## 1. The deprecated usage is still available
## 2. Unicode::Map issues warnings if $WARNINGS & WARN_DEPRECATION
##
# Before `make install' is performed this script should be runnable with
# `make test'. After `make install' it should work as `perl test.pl'
######################### We start with some black magic to print on failure.
# Change 1..1 below to 1..last_test_to_print .
# (It may become useful if the test is moved to ./t subdirectory.)
BEGIN { $| = 1; print "1..5\n"; }
END {print "not ok 1\n" unless $loaded;}

print "ok 1\n";
