icon-naming-utils is a script for maintaining backwards compatibility with
current desktop icon themes, while migrating to the names specified in the
Icon Naming Specification [1].

The recommended method for using icon-naming-utils is via the Makefile
scripts used to build a project. An example of how to do this, in an
automake-parsed Makefile.am, is shown below:

size = 32x32
context = actions

iconsdir = $(themedir)/$(size)/$(context)

install-data-local: install-iconsDATA
	(cd $(DESTDIR)$(themedir)/$(size) && $(ICONMAP) -c $(context))


And in configure.{in,ac} you should have:

# Define the toplevel path here
AC_SUBST(themedir, "\${datadir}/icons/Theme")

UTILS_REQUIRED=0.8.2

AC_MSG_CHECKING([icon-naming-utils >= $UTILS_REQUIRED])
PKG_CHECK_EXISTS(icon-naming-utils >= $UTILS_REQUIRED,
                 have_utils=yes, have_utils=no)
if test "x$have_utils" = "xyes"; then
   UTILS_PATH="`$PKG_CONFIG --variable=program_path icon-naming-utils`"
   ICONMAP="$UTILS_PATH/icon-name-mapping"
   AC_SUBST(ICONMAP)
   AC_MSG_RESULT([yes])
else
   AC_MSG_RESULT([no])
   AC_MSG_ERROR([icon-naming-utils >= $UTILS_REQUIRED is required to build
                 and install tango-icon-theme])
fi

In this example, we define $(themedir) to point to the theme's install
path, and ICONMAP gets defined as the path to the icon-name-mapping script.
This script is not installed in a normal $(bindir) path, as it is not intended
to be run by users by hand, but to be called from scripts, such as Makefiles.
