New Revision: 343020
URL: https://svnweb.freebsd.org/changeset/base/343020
Log:
This new version of bluetooth-config.sh tries to follow the style of other
shell scripts in base, removes the bogus "copyleft", adds the BeerWare license
header and uses rc.subr(8) new 'enable' keyword for adding entries in
rc.conf(5).
