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.
