+===== Bookkeeping information within Ganga =====
+A simple method that can be added to the ~/.ganga.py to access information directly from the BK can be seen below:
+<code python>
+def getBKInfo ( evttype )  :
+    from subprocess import Popen, PIPE
+    serr = open ( '/dev/null' )
+    pipe = Popen ( [ 'get_bookkeeping_info'  , str(evttype) ] ,
+                   env    = os.environ ,
+                   stdout = PIPE       ,
+                   stderr = serr       )
+    stdout = pipe.stdout
+    ts = {}
+    result = {}
+    for line in stdout :
+        try :
+            value = eval ( line )
+        except :
+            continue
+        if not isinstance ( value    , tuple ) : continue
+        if not isinstance ( value[0] , str   ) : continue
+        if not isinstance ( value[1] , str   ) : continue
+        if not isinstance ( value[2] , str   ) : continue
+        if result.has_key ( value[0] ) : continue
+        result [ value[0] ] = value[1:]
+    return result
+</code>
+In this case two additional files 'get_bookkeeping_info' and 'dirac-bookkeeping-get-prodinfo-eventtype.py' are required to be saved locally in your ~/bin/ directory.
