This sets @INC to 'lib, and unless we're already at the top level will chdir '..' [on the assumption that we are starting in t].

# This is a replacement for the old BEGIN preamble which heads (or
|
|
# should head) up every core test program to prepare it for running.
|
|
# Now instead of:
|
|
#
|
|
# BEGIN {
|
|
# chdir 't' if -d 't';
|
|
# @INC = '../lib';
|
|
# }
|
|
#
|
|
# Its primary purpose is to clear @INC so core tests don't pick up
|
|
# modules from an installed Perl.
|
|
#
|
|
# t/TEST will use -MTestInit. You may "use TestInit" in the test
|
|
# programs but it is not required.
|
|
#
|
|
# P.S. This documentation is not in POD format in order to avoid
|
|
# problems when there are fundamental bugs in perl.
