	For the autoconf side, the only thing to do is to drop
AC_ARG_PROGRAM
	somewhere, what enables the --program options to configure.

	Then you need to put the @program_transform_name@ somewhere in
the Makefile.

	Here are the relevant parts of autoconf's doc:

Transforming Program Names When Installing
==========================================

   Autoconf supports changing the names of programs when installing
them.  In order to use these transformations, `configure.in' must call
the macro `AC_ARG_PROGRAM'.

 - Macro: AC_ARG_PROGRAM
     Place in output variable `program_transform_name' a sequence of
     `sed' commands for changing the names of installed programs.

     If any of the options described below are given to `configure',
     program names are transformed accordingly.  Otherwise, if
     `AC_CANONICAL_SYSTEM' has been called and a `--target' value is
     given that differs from the host type (specified with `--host' or
     defaulted by `config.sub'), the target type followed by a dash is
     used as a prefix.  Otherwise, no program name transformation is
     done.

Transformation Rules
--------------------

   Here is how to use the variable `program_transform_name' in a
`Makefile.in':

     PROGRAMS=cp ls rm
     install:
             for p in $(PROGRAMS); do \
               $(INSTALL_PROGRAM) $$p $(bindir)/`echo $$p|sed '$(transform)'`; \
             done
     
     uninstall:
             for p in $(PROGRAMS); do \
               rm -f $(bindir)/`echo $$p|sed '$(transform)'`; \
             done
