+ *  \brief This section describes the host structure of MSG
+ * (#m_host_t) and the functions for managing it.
+ *  
+ *  A <em>location</em> (or <em>host</em>) is any possible place where
+ *  a process may run. Thus it may be represented as a
+ *  <em>physical resource with computing capabilities</em>, some
+ *  <em>mailboxes</em> to enable running process to communicate with
+ *  remote ones, and some <em>private data</em> that can be only
+ *  accessed by local process.
