Revision 1.1, Tue Aug 26 17:47:24 2014 UTC (9 years, 9 months ago) by jsing
Branch: MAIN
Move openssl(1) from /usr/sbin/openssl to /usr/bin/openssl, since it is not
a system/superuser binary. At the same time, move the source code from its
current lib/libssl/src/apps location to a more appropriate home under
usr.bin/openssl.
