$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.
