X-Git-Tag: rev_ivi_2015_02_04~10780
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7ac9d05f48d921fb98c370e4f9d248f8b382fb30;p=scm%2Fbb%2Ftizen-distro.git

bitbake: bitbake-dumpsig: introduce command line and error handling

This utility doesn't take any special arguments, but it's nice if it at
least knows how to deal with no arguments, --help and errors properly.
