+$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.
