dnl ************************************************************

dnl Guidelines for updating these definitions:
dnl 1) If the library source code has changed at all since the last update,
dnl then increment REVISION.
dnl 2) If any interfaces have been added, removed, or changed since the last
dnl update, increment CURRENT, and set REVISION to zero.
dnl 3) If any interfaces have been added since the last public release, then
dnl increment AGE.
dnl 4) If any interfaces have been removed since the last public release, then
dnl set AGE to zero.

dnl The most recent interface number that this library implements.
define(AC_JAS_LT_CURRENT, 1)

dnl The implementation number of the current interface.
define(AC_JAS_LT_REVISION, 0)

dnl The difference between the newest and oldest interfaces that this library
dnl implements.  In other words, the library implements all of the interface
dnl numbers in the range from current - age to current.
define(AC_JAS_LT_AGE, 0)

dnl The release number of the library.
define(AC_JAS_LT_RELEASE, AC_JAS_MAJOR_VERSION.AC_JAS_MINOR_VERSION)
