+ This is the main URL under which Aegir will be controlled. A Virtual
+ Host and Drupal website with the Aegir frontend modules
+ ("hostmaster") will be created for that domain.
+ .
+ Leave empty to use the default (the domain of this machine).

+Description: Database server hostname:
+ This is the hostname at which the database server is available.

+Template:aegir/makefile
+Type: string
+Description: Makefile used to create the platform:
+ The makefile passed to drush_make to create the hostmaster
+ platform. Note that this needs specific modules and profiles for the
+ frontend to work correctly, be careful in changing this from the
+ default.
+ .
+ If this is left empty, Aegir will use its internal makefile.

+Description: frontend of the Aegir hosting system
+ Hostmaster is a component of the Aegir hosting system.
+ .
+ Aegir is a set of contributed modules for Drupal that aims to solve
+ the problem of managing a large number of Drupal sites. It does this
+ by providing you with a simple Drupal based hosting front end for
+ your entire network of sites. To deploy a new site you simply have to
+ create a new Site node. To backup or upgrade sites, you simply manage
+ your site nodes as you would any other node.
+ .
+ The hostmaster component provides the frontend that drives the
+ backend. It's made up of a regular Drupal site with a custom install
+ profile, module and theme.
+ .
+ This meta-package will dynamically install the frontend using drush
+ and provision.
