+ \param ref An entry_ref with an attribute holding data for catalog
lookup.
+ \param localizedFileName A pre-allocated BString object for the result
+ of the lookup.
+ \param traverse A boolean to decide if symlinks are to be traversed.
+ \return
+ - \c B_OK: success
+ - \c B_ENTRY_NOT_FOUND: failure. Attribute not found, entry not found
+ in catalog, etc
+ - other error codes: failure
+
+ Attribute format: "signature:context:string"
+ (no colon in any of signature, context and string)
+
+ Lookup is done for the top preferred language, only.
+ Lookup fails if a comment is present in the catalog entry.
