#### 16.5.16 Adding casing exceptions

A set of case exceptions can be declared in this file. Each case exception is put inside the tag `<word>` or `<substring>`. These exceptions are used by GPS to set identifiers or keywords case when editing case insensitive languages (except if corresponding case is set to Unchanged). see The Preferences Dialog.
