X-Git-Tag: submit/2.0alpha-wayland/20121130.004132~9^2~140
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=329c15714be90d3fc2d9054f80cb14fa325dc959;p=profile%2Fivi%2Forg.tizen.video-player.git

Add libtool versioning

The versioning is automatic.  For now, soname-major is 0.  With
the 1.0.0 release it will jump to 1 and stay there forever.
