- * \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.
