Actually, you don't. The verbose support is included by default.  
However if you want to improve performance by striping out the  
verbose code support then you should do 'make no-verbose'.

Field 'oil.verbose' provides the API described in 'http:// 
loop.luaforge.net/docs_Verbose.html' thus you can use  
'oil.verbose:level(2)' to enable messages up to verbose level 2 or  
'oil.verbose:flag("invoke", true)' to enable messages about request  
invocation.

The list of all OiL verbose flags are defined in file 'lua/oil/ 
verbose.lua' and the verbose levels are defined as follows:

1: Operation invocation and dispatching;
2: GIOP request and reply processing;
3: Mutual exclusion channel access (concurrent mode);
4: GIOP message creation and handling (i.e. requests and replies);
5: Socket channels creation and handling (i.e. connection and  
transport);
6: Value (un)marshaling;
7: Hexadecimal view of marshaled streams;
8: Creation of IDL descriptors and internal IR operation;

To debug the application I suggest to use levels 1 or 2. However to  
find out if OiL is doing something wrong you shall enable levels 5 or  
6 and send me the log.

For debugging application it is also useful to enable verbose  
messages about value mashaling. This can be done individually in the  
application code by commands 'oil.verbose:flag("marshal", true)' and  
'oil.verbose:flag("unmarshal", true)'. But be careful because the log  
may become really big in most cases.

Thanks for your interest.
