dnl Making releases:
dnl   PANGO_MICRO_VERSION += 1;
dnl   PANGO_INTERFACE_AGE += 1;
dnl   PANGO_BINARY_AGE += 1;
dnl if any functions have been added, set PANGO_INTERFACE_AGE to 0.
dnl if backwards compatibility has been broken,
dnl set PANGO_BINARY_AGE _and_ PANGO_INTERFACE_AGE to 0.

dnl We do the version number components as m4 macros
dnl so that we can base configure --help output off
dnl of them.
