Author: imp Date: Thu May 23 17:18:48 2019 New Revision: 348175 URL: https://svnweb.freebsd.org/changeset/base/348175 Log: Implement "VARS_ONLY=1" via special command line args Add -v to print TYPE REVISION BRANCH RELEASE VERSION RELDATE variables Add -V var to print var's value Both of these in ${var}="${val}" format suitable for eval $(sh newvers.sh -v) in shell scripts / makefiles. Add -c to print the copyright / license comment text only. Document these, and remove soon-to-be obsolete comment. Minor code motion as well bunded here to put functions after VARS_ONLY and command line argument parsing.
