Configuration file

 it is a text file (only file-system storage supported)

 no native support for advanced text processing (like define,

include, etc), but very easy and simple to integrate with M4

 the file is loaded and processed only at startup (not used at

runtime)

 currently there is no support for re-loading the configuration file

at runtime – you need to restart the application; fortunately the

most changeable data is configured via DB, where reload is

possible.

Ex:

openser -f openser.cfg
