//-----------------------------------------------------------------------
// * The Currency Format plugin  rewrites the currency  into a much more
//   readable format, especially with larger numbers.
//
//   This plugin was originally inspired by the scriptlet I did for RMVX
//   and RMVXA to split larger currency numbers with commas, thus 100000
//   is shown as 100,000.

 Currency Format Plugin v1.0

 ========================
  * Options
 ========================
  The plugin has two parameter options:

  "Comma" - Separates numbers with commas, so 100000 becomes 100,000.

  "Suffix" - Replaces trailing zeros with words, i.e. "k" for thousands and "m"
  for millions. Since the maximum allowed value for gold in RMMV is 99,999,999
  this is rounded up to 100,000,000, with the output being "100m". Hence, there
  is no "b" for billions, etc.

 ========================
  * Plugin Commands
 ========================
  This plugin does not provide plugin commands.
