3727 dnl You might wonder (I did) why epaths.h is generated by running make,
3728 dnl rather than just letting configure generate it from epaths.in.
3729 dnl One reason is that the various paths are not fully expanded (see above);
3730 dnl eg gamedir=${prefix}/var/games/emacs.
3731 dnl Secondly, the GNU Coding standards require that one should be able
3732 dnl to run `make prefix=/some/where/else' and override the values set
3733 dnl by configure. This also explains the `move-if-change' test and
3734 dnl the use of force in the `epaths-force' rule in Makefile.in.
