   Sourcehut is a Python and Go based set of applications.
   This NixOS module also provides basic configuration integrating Sourcehut into locally running

   The <literal>hostName</literal> option is used internally to configure the nginx

  <title>Configuration</title>

  <para>
   All configuration parameters are also stored in
   <literal>/etc/sr.ht/config.ini</literal> which is generated by
   the module and linked from the store to ensure that all values from <literal>config.ini</literal>
   can be modified by the module.

  <title>Using an alternative webserver as reverse-proxy (e.g. <literal>httpd</literal>)</title>
  <para>
   By default, <package>nginx</package> is used as reverse-proxy for <package>sourcehut</package>.
   However, it's possible to use e.g. <package>httpd</package> by explicitly disabling
   <package>nginx</package> using <xref linkend="opt-services.nginx.enable" /> and fixing the
   <literal>settings</literal>.
