dnl The libtool version numbers (DVDREAD_LT_*); Don't even think about faking this!

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 = 0;

dnl    DVDREAD_LT_CURRENT ++;

dnl    if (any interfaces have been _added_ since last release)

dnl       AGE ++;

dnl }

dnl

dnl If you want to know more about what you are doing, here are some details:

dnl  * DVDREAD_LT_CURRENT is the current API version

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

dnl    libname.so.(DVDREAD_LT_CURRENT - DVDREAD_LT_AGE).DVDREAD_LT_REVISION.DVDREAD_LT_AGE
