3# This is written in a peculiar style, since we're trying to avoid
4# most of the constructs we'll be testing for.  (This comment is
5# probably obsolete on the avoidance side, though still currrent
6# on the peculiarity side.)
7
8# t/TEST and t/harness need to share code. The logical way to do this would be
9# to have the common code in a file both require or use. However, t/TEST needs
10# to still work, to generate test results, even if require isn't working, so
11# we cannot do that. t/harness has no such restriction, so it is quite
12# acceptable to have it require t/TEST.
13
14# In which case, we need to stop t/TEST actually running tests, as all
15# t/harness needs are its subroutines.
