14dnl this macro
15dnl - AC_SUBST's PACKAGE_VERSION_MAJOR, _MINOR, _MICRO
16dnl - AC_SUBST's PACKAGE_VERSION_RELEASE,
17dnl    which can be used for rpm release fields
18dnl - doesn't call AM_INIT_AUTOMAKE anymore because it prevents
19dnl   maintainer mode from running correctly
20dnl
21dnl don't forget to put #undef PACKAGE_VERSION_RELEASE in acconfig.h
22dnl if you use acconfig.h

37dnl requires AC_INIT to be called before
38dnl For projects using a fourth or nano number in your versioning to indicate
39dnl development or prerelease snapshots, this macro allows the build to be
40dnl set up differently accordingly.
41
42dnl this macro:
43dnl - parses AC_PACKAGE_VERSION, set by AC_INIT, and extracts the nano number
44dnl - sets the variable PACKAGE_VERSION_NANO
45dnl - sets the variable PACKAGE_VERSION_RELEASE, which can be used
46dnl   for rpm release fields
47dnl - executes ACTION-IF-NO-NANO or ACTION-IF-NANO
