/**
 * \file
 * \brief C API: Message Catalog Wrappers
 *
 * This C API provides look-alike functions that deliberately resemble
 * the POSIX catopen, catclose, and catgets functions.  The underlying
 * implementation is in terms of ICU resource bundles, rather than
 * POSIX message catalogs.
 *
 * The ICU resource bundles obey standard ICU inheritance policies.
 * To facilitate this, sets and messages are flattened into one tier.
 * This is done by creating resource bundle keys of the form
 * <set_num>%<msg_num> where set_num is the set number and msg_num is
 * the message number, formatted as decimal strings.
 *
 * Example:  Consider a message catalog containing two sets:
 *
 * Set 1: Message 4  = "Good morning."
 *        Message 5  = "Good afternoon."
 *        Message 7  = "Good evening."
 *        Message 8  = "Good night."
 * Set 4: Message 14 = "Please "
 *        Message 19 = "Thank you."
 *        Message 20 = "Sincerely,"
 *
 * The ICU resource bundle source file would, assuming it is named
 * "greet.txt", would look like this:
 *
 * greet
 * {
 *     1%4  { "Good morning." }
 *     1%5  { "Good afternoon." }
 *     1%7  { "Good evening." }
 *     1%8  { "Good night." }
 * 
 *     4%14 { "Please " }
 *     4%19 { "Thank you." }
 *     4%20 { "Sincerely," }
 * }
 *
 * The catgets function is commonly used in combination with functions
 * like printf and strftime.  ICU components like message format can
 * be used instead, although they use a different format syntax.
 * There is an ICU package, icuio, that provides some of
 * the POSIX-style formatting API.
