/*
* ISC Message Catalog
*
* Message catalogs aid internationalization of applications by allowing
* messages to be retrieved from locale-specific files instead of
* hardwiring them into the application. This allows translations of
* messages appropriate to the locale to be supplied without recompiling
* the application.
*
* Notes:
* It's very important that message catalogs work, even if only the
* default_text can be used.
*
* MP:
* The caller must ensure appropriate synchronization of
* isc_msgcat_open() and isc_msgcat_close(). isc_msgcat_get()
* ensures appropriate synchronization.
*
* Reliability:
* No anticipated impact.
*
* Resources:
* <TBS>
*
* Security:
* No anticipated impact.
*
* Standards:
* None.
