Comment (by ryandesign):

 Assuming I have not overlooked some stdout capability in Apple's xar,
 possible solutions I see:

 * Add
 [https://github.com/mackyle/xar/commit/ddea2e4b53b6b2cfdd0d13c6beaac0978330c2a2
 the stdout capability] to Apple's xar.
 * Revert to mackyle's xar 1.6.1. (Apple's xar is already available at
 /usr/bin/xar.)
 * Offer two ports, one for Apple's xar and one for mackyle's xar.
