+      The statgrab library provides a cross-platform interface to getting
       system statistics. Each of the function calls returns a structure
       containing statistics. See the manual page for each individual
       function for more details on usage.
     </para>
     <para>
-      The library was originally written to support the i-scream central
-      monitoring system, but has since become a standalone package. It
-      has been ported to work on Linux, FreeBSD, and Solaris.
+      <function>sg_init</function> must be the first
+      function you call before you start to use libstatgrab; it performs all
+      the one-time initialisation operations that need setuid/setgid
+      privileges. For instance, on *BSD it opens a descriptor to be able to
+      read kernel structures later on, and on Solaris it reads the device
+      mappings that in some cases are only accessible by root (machines with
+      a /dev/osa). Once this has run, the other libstatgrab functions no longer 
+      need elevated privileges. It is therefore a good idea to call
+      <function>sg_drop_privileges</function>, which discards
+      setuid and setgid privileges, immediately after you call
+      <function>sg_init</function>, unless your application has
+      another reason for needing setuid or setgid privileges.
     </para>
+    <para>
+      <function>sg_init</function> and
+      <function>sg_drop_privileges</function> return 0 on success, and
+      non-zero on failure.
