+      <emphasis remap='B'>PAM</emphasis> is a system of libraries
+      that handle the authentication tasks of applications (services)

+      (Application Programming Interface - API) that privilege granting
+      programs (such as

+        PAM transaction. It is the first of the PAM functions that needs to
+        be called by an application. The transaction state is contained
+        entirely within the structure identified by this handle, so it is
+        possible to have multiple transactions in parallel. But it is not
+        possible to use the same handle for different transactions, a new
+        one is needed for every new context.
