 9.4.2 Transformation Examples
 -----------------------------
 
 These transformations are useful with programs that can be part of a
 cross-compilation development environment.  For example, a
 cross-assembler running on a Sun 4 configured with
 `--target=i960-vxworks' is normally installed as `i960-vxworks-as',
 rather than `as', which could be confused with a native Sun 4 assembler.
 
    You can force a program name to begin with `g', if you don't want
 GNU programs installed on your system to shadow other programs with the
 same name.  For example, if you configure GNU `diff' with
 `--program-prefix=g', then when you run `make install' it is installed
 as `/usr/local/bin/gdiff'.
 
    As a more sophisticated example, you could use
      --program-transform-name='s/^/g/; s/^gg/g/; s/^gless/less/'
    to prepend `g' to most of the program names in a source tree,
 excepting those like `gdb' that already have one and those like `less'
 and `lesskey' that aren't GNU programs.  (That is assuming that you
 have a source tree containing those programs that is set up to use this
 feature.)
 
    One way to install multiple versions of some programs simultaneously
 is to append a version number to the name of one or both.  For example,
 if you want to keep Autoconf version 1 around for awhile, you can
 configure Autoconf version 2 using `--program-suffix=2' to install the
 programs as `/usr/local/bin/autoconf2', `/usr/local/bin/autoheader2',
 etc.
