+    <<-EOF
+The install command installs local or remote gem into a gem repository.
+
+For gems with executables ruby installs a wrapper file into the executable
+directory by deault.  This can be overridden with the --no-wrappers option.
+The wrapper allows you to choose among alternate gem versions using _version_.
+
+For example `rake _0.7.3_ --version` will run rake version 0.7.3 if a newer
+version is also installed.
