3750 dnl You might wonder (I did) why epaths.h is generated by running make,
3751 dnl rather than just letting configure generate it from epaths.in.
3752 dnl One reason is that the various paths are not fully expanded (see above);
3753 dnl eg gamedir=${prefix}/var/games/emacs.
3754 dnl Secondly, the GNU Coding standards require that one should be able
3755 dnl to run `make prefix=/some/where/else' and override the values set
3756 dnl by configure. This also explains the `move-if-change' test and
3757 dnl the use of force in the `epaths-force' rule in Makefile.in.
