+%% Managing conditional debug functions
+%%
+%% The main idea with the debug_fun's is to allow test programs
+%% to control the internal behaviour of CosTransactions.
+%%
+%% First should calls to ?eval_debug_fun be inserted at well
+%% defined places in CosTransaction's code. E.g. in critical situations
+%% of startup, transaction commit, backups etc.
+%%
+%% Then compile CosTransactions with the compiler option 'debug'.
+%%
+%% In test programs ?activate_debug_fun should be called
+%% in order to bind a fun to the debug identifier stated
+%% in the call to ?eval_debug_fun.
