dnl immediately before every release do:
dnl ===================================
dnl if (the interface is totally unchanged from previous release)
dnl DVDREAD_LT_REVISION ++;
dnl else { /* interfaces have been added, removed or changed */

dnl * DVDREAD_LT_REVISION is an internal revision number which is increased when the API
dnl itself did not change
dnl * DVDREAD_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
