   ### Bootleg hot upgrade task

   In the following description we assume that the development 
   enviroinment is organized in this way (the build and 
   the production places can be the same machine):
-  
+
     * the development machine - where you edit and 
       test locally your app source files;
-  
+
     * the build machine - the computer where you will transfer to
       and compile the committed source code;
-  
+
     * the production server - the server where you will deploy 
       (transfer to and run) the code previously compiled on 
       the build machine.

   Bootleg helps you in the hot upgrade process providing 
   some specific tasks:

   ### A step-by-step example
-  
+
   Given you have configured the first version of your app with all
   the needed and appropriately customized Bootleg configuration files, 
   you can go through the following steps to release and run the 
   first version and subsequentely hot upgrade it to the newest
   versions:
-  
+
   First version of your app:
-  
+
     # Step 1 - deploy the first version of your app
       edit the version number of your in the mix.exs file 
       (or in the file if you use an external reference),
       to the first version, e.g. 0.1.0;
-  
+
     # Step 2 - Commit
       commit the changes you've made in step 1;
-  
+
     # Step 3 - Build the first version
       use `mix bootleg.build` (not bootleg.build_upgrade!) to build 
       your first version;
-  
+
     # Step 4 - Deploy the first version
       use `mix bootleg.deploy` (not bootleg.build_upgrade!) to deploy 
       your first version;
-  
+
     # Step 5 - Run the first version
       use `mix bootleg.start` to run the app
-  
+
     now your first version is up and running. To upgrade it 
     to the future version, you have to follow these steps instead.
-  
+
   Following versions:
-  
+
     # Step 1 - update the version number
       e.g. 0.2.0
-  
+
     # Step 2 - Commit
-  
+
     # Step 3 - Build the new version
       use `mix bootleg.build_upgrade`
-  
+
     # Step 4 - Deploy the new version
       use `mix bootleg.deploy_upgrade`
-  
+
     # Step 5 - Hot upgrade the new version
       use `mix bootleg.hot_upgrade`
-  
+
     (or you can execute just the `bootleg.upgrade` 
     that packs the previous tasks together if you don't need to
     manually adjust the created `appup` file)
-  
+
     Now you have an upgraded version running. But if you stop
     and restart it, the previous version will be launched instead
     of the most recent. This is useful because if your new version
