+The build command allows you to create a gem from a ruby gemspec.
+
+The best way to build a gem is to use a Rakefile and the Gem::PackageTask
+which ships with RubyGems.
+
+The gemspec can either be created by hand or extracted from an existing gem
+with gem spec:
+
+  $ gem unpack my_gem-1.0.gem
+  Unpacked gem: '.../my_gem-1.0'
+  $ gem spec my_gem-1.0.gem --ruby > my_gem-1.0/my_gem-1.0.gemspec
+  $ cd my_gem-1.0
+  [edit gem contents]
+  $ gem build my_gem-1.0.gemspec
+    EOF
+  end

+    if File.exist? gemspec then

+

+        Gem::Package.build spec, options[:force]
+      else

+      end
+    else
+      alert_error "Gemspec file not found: #{gemspec}"
