def explain_picklejar(dir, catch_exceptions=True):
r"""
Given a directory or a .tar.bz2 of pickles, we unpickle each of
them three times: once with cPickle, once with explain_pickle
with in_current_sage=True, and once with explain_pickle
with in_current_sage=False.
We verify that each of these gives the same answer (where we check
using repr(a)==repr(b), in case equality is not defined on all
of these objects).
INPUT::
dir -- string; a directory or name of a .tar.bz2 file that
decompresses to give a directory full of pickles.
catch_exceptions -- boolean; default True: if True, then
unpickling exceptions will be caught (and if all three
unpicklers raise an exception, then that will be counted
as a match). If False, then exceptions will not be caught,
and will terminate this function.
EXAMPLES:
sage: std = os.environ['SAGE_DATA'] + '/extcode/pickle_jar/pickle_jar.tar.bz2'
sage: from sage.misc.explain_pickle import *
sage: explain_picklejar(std) # long time (~45s on my computer)
