dnl AGE = LT_AGE

dnl SONAME of the emerging library is LT_CURRENT - LT_AGE.

dnl The linker will do no finer checks. Especially no age range check for

dnl the cdrskin binary. If SONAME matches, then the couple starts.

dnl iso_lib_version(). It returns the major, minor and micro revision of the

dnl comply to the usual ways of configure.ac . I.e. now *officially* this is
