14 /* Freeorion aims to have exceptions handled and operation continue normally.
15 An example of good exception handling is the exceptions caught around config.xml loading.
16 After catching and informing the user it continues normally with the default values.
17
18 An exception that can not be handled should allow freeorion to crash and keep
19 a complete stack trace of the intial exception.
20 Some platforms do not support this behavior.
21
22 When FREEORION_CAMAIN_KEEP_BACKTRACE is defined, do not catch an unhandled exceptions,
23 unroll and hide the stack trace, print a message and still crash anyways. */
