/**

* \file
|
|
* Localised message support (interface).
|
|
*
|
|
* The messages module loads a file of keys and associated strings, and
|
|
* provides fast lookup by key. The messages file consists of key:value lines,
|
|
* comment lines starting with #, and other lines are ignored. Use
|
|
* messages_load() to read the file into memory. To lookup a key, use
|
|
* messages_get("key").
|
|
*
|
|
* It can also load additional messages files into different contexts and allow
|
|
* you to look up values in it independantly from the standard shared Messages
|
|
* file table. Use the _ctx versions of the functions to do this.
