+h4. +console+
 
 The +console+ command lets you interact with your Rails application from the command line. On the underside, +script/console+ uses IRB, so if you've ever used it, you'll be right at home. This is useful for testing out quick ideas with code and changing data server-side without touching the website.
 
-h4. dbconsole
+h4. +dbconsole+
 
 +dbconsole+ figures out which database you're using and drops you into whichever command line interface you would use with it (and figures out the command line parameters to give to it, too!). It supports MySQL, PostgreSQL, SQLite and SQLite3.
 
-h4. plugin
+h4. +plugin+
 
 The +plugin+ command simplifies plugin management; think a miniature version of the Gem utility. Let's walk through installing a plugin. You can call the sub-command *discover*, which sifts through repositories looking for plugins, or call *source* to add a specific repository of plugins, or you can specify the plugin location directly.

+h4. +server+ with Different Backends
 
 Many people have created a large number different web servers in Ruby, and many of them can be used to run Rails. Since version 2.3, Rails uses Rack to serve its webpages, which means that any webserver that implements a Rack handler can be used. This includes WEBrick, Mongrel, Thin, and Phusion Passenger (to name a few!).

 Let's take a look at some of these 80 or so rake tasks.
 
-h5. db: Database
+h5. +db:+ Database
 
 The most common tasks of the +db:+ Rake namespace are +migrate+ and +create+, and it will pay off to try out all of the migration rake tasks (+up+, +down+, +redo+, +reset+). +rake db:version+ is useful when troubleshooting, telling you the current version of the database.
 
-h5. doc: Documentation
+h5. +doc:+ Documentation
 
 If you want to strip out or rebuild any of the Rails documentation (including this guide!), the +doc:+ namespace has the tools. Stripping documentation is mainly useful for slimming your codebase, like if you're writing a Rails application for an embedded platform.
 
-h5. gems: Ruby gems
+h5. +gems:+ Ruby gems
 
 You can specify which gems your application uses, and +rake gems:install+ will install them for you. Look at your environment.rb to learn how with the *config.gem* directive.
 
 NOTE: +gems:unpack+ will unpack, that is internalize your application's Gem dependencies by copying the Gem code into your vendor/gems directory. By doing this you increase your codebase size, but simplify installation on new hosts by eliminating the need to run +rake gems:install+, or finding and installing the gems your application uses.
 
-h5. notes: Code note enumeration
+h5. +notes:+ Code note enumeration
 
 These tasks will search through your code for commented lines beginning with "FIXME", "OPTIMIZE", "TODO", or any custom annotation (like XXX) and show you them.
 
-h5. rails: Rails-specific tasks
+h5. +rails:+ Rails-specific tasks
 
 In addition to the +gems:unpack+ task above, you can also unpack the Rails backend specific gems into vendor/rails by calling +rake rails:freeze:gems+, to unpack the version of Rails you are currently using, or +rake rails:freeze:edge+ to unpack the most recent (cutting, bleeding edge) version.

 The tmp directory is, like in the *nix /tmp directory, the holding place for temporary files like sessions (if you're using a file store for files), process id files, and cached actions.
