# Allow the user GNUmakefile to define xxx_INTERFACE_VERSION to
# replace the default INTERFACE_VERSION for this library.
# Effect of the value of xxx_INTERFACE_VERSION -
# suppose your library is libgnustep-base.1.0.0 - if you do nothing,
# INTERFACE_VERSION=1, and we prepare the symlink
# libgnustep-base.so.1 --> libgnustep-base.so.1.0.0 and tell the
# linker that it should remember that any application compiled
# against this library need to use version .1 of the library. So at
# runtime, the dynamical linker will search for libgnustep-base.so.1.
# This is important if you install multiple versions of the same
# library. The default is that if you install a new version of a
# library with the same major number, the new version replaces the
# old one, and all applications which were using the old one now use
# the new one. If you install a library with a different major
# number, the old apps will still use the old library, while newly
# compiled apps will use the new one.
# If you redefine xxx_INTERFACE_VERSION to be for example 1.0, then
# we prepare the symlink libgnustep-base.so.1.0 -->
# libgnustep-base.so.1.0.0 instead, and tell the linker to remember
# 1.0. So at runtime, the dynamic linker will search for
# libgnustep-base.so.1.0. The effect of changing
# xxx_INTERFACE_VERSION to major.minor as in this example is that if
# you install a new version with the same major.minor version, that
# replaces the old one also for old applications, but if you install
# a new library with the same major version but a *different* minor
# version, that is used in new apps, but old apps still use the old
