 =head1 SYNOPSIS
 
     use base CGIAppBase;
-
+    
+    sub a_run_method {
+      my $self = shift;
+    
+      my $dbh = $self->dbh();
+      my $sql = $self->retr_select_sql('AGENCY_X_ALL');
+      my $tmp_dir =$self->get_config_param('ABSOULTE_PATH.tmp_dir');
+      my $stuff_aref = $dbh->selectcol_arrayref($sql);
+      #...                  
+   }
+   
 =head1 DESCRIPTION
 
- There are no public methods. 
+ MVHub::CGIAppBase is the class all our other classes should inherit 
+ from. It contains methods for getting the object's database handle, 
+ the variables contained in the configuration file and the SQL 
+ statements stored in app-mvhub/conf/sql_select.lib
+
+=head1 METHODS
+  
+  dbh()
+  
+   returns a database handle 
+
+
+  get_config_param($PARAM_NAME)
+  
+    Given the name of a paramter, returns the value stored in the 
+    application config file. 
+    
+    The application configuration file
+    is currently either /var/www/mvhub/$USER/conf/mvh.conf or 
+    /var/www/mvhub/$USER/conf/nsp.conf (though you should not
+    depend on these files remaining in these places. 
+        
+  retr_select_sql($SQL_STATEMENT_NAME)
+
+    Given the name of a sql SELECT statement, returns the SQL for that
+    statement. Currently the file the SQL statements are stored in
+    is: app-mvhub/conf/sql_select.lib, though you should not depend
+    on this location. ---And you should need to depend on a hard coded
+    path as this is handled internally for you by CGIAppBase.

 =head1 BUGS
 
-CGIAppBase is used by AgencyAccount.pm and (the emerging) AgencyRecord.pm
-
-CGIAppBase is not used by DataEntryAccount.pm, Guide.pm so these modules all have duplicate code
+CGIAppBase is used by AgencyAccount.pm and Guide.pm but not other 
+classes. Much of the code, agency_form.pl and program.pl in particular 
+don't use CGI::Application as they are entirely procedural.
