$USAGE
Install emacs quickly
-n, --dry-run print installation commands instead of
executing them
-f, --force install even files that haven't changed
-v, --verbose print messages describing what is done
-p, --prune prune old generated files
-P, --no-prune don't prune old generated files (default)
--prune-only prune old generated files, but don't install
--help display this help and exit
--version output version information and exit
$me install emacs \`incrementally,' that is, it will
install only those files that have changed since the last time it was
invoked, and remove any obsolete files from the installation
directories. It also uses hard-links into the source and build trees to
do the install, so it uses much less space than the default Makefile
install target; however, this also means that $me can
not install onto a disk partition other than the one on which the source
and build directories reside.
Optionally, $me can also remove old versions of
automatically generated files that are version-specific (such as the
versioned emacs executables in the \`src' directory, and the DOC-* files
in the \`etc' directory). The latter action is called \`pruning,' and
can be enabled using the \`-p' or \`--prune' options.
