TOPLEVEL_VERSION is an (auto)make variable, defined in aclocal.m4:
. $srcdir/VERSION
FULL_VERSION=$MAJOR_VERSION.$MINOR_VERSION.$PATCH_LEVEL
MICRO_VERSION=$PATCH_LEVEL
TOPLEVEL_VERSION=$FULL_VERSION
The first line above reads in the VERSION file, the second constructs the
FULL_VERSION from the various parts defined in the VERSION file...
Notice that aclocal.m4 also calls AC_SUBST on each $*_VERSION part, so these
variables are available in makefiles...
Cheers,
Reinhold
