-%%--------------- DEBUG FUNCTIONS --------------------------------------
-%% 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.
