dnl immediately before every release do:
dnl ===================================
dnl if (the interface is totally unchanged from previous release)
dnl    DVDNAV_LT_REVISION ++;
dnl else { /* interfaces have been added, removed or changed */
dnl    DVDNAV_LT_REVISION = 0;
dnl    DVDNAV_LT_CURRENT ++;
dnl    if (any interfaces have been _added_ since last release)
dnl       AGE ++;
dnl    if (any interfaces have been _removed_ or _incompatibly changed_)
dnl       AGE = 0;
dnl }
dnl 
dnl If you want to know more about what you are doing, here are some details:
dnl  * DVDNAV_LT_CURRENT is the current API version
dnl  * DVDNAV_LT_REVISION is an internal revision number which is increased when the API
dnl    itself did not change
dnl  * DVDNAV_LT_AGE is the number of previous API versions still supported by this library
dnl  * libtool has its own numbering scheme, because local library numbering schemes
dnl    are platform dependent
dnl  * in Linux, the library will be named
dnl    libname.so.(DVDNAV_LT_CURRENT - DVDNAV_LT_AGE).DVDNAV_LT_AGE.DVDNAV_LT_REVISION
