[cp-patches] FYI: [cp-tools] Extend currencygen to also output supplemental week data

[Andrew John Hughes]

With new releases of CLDR, the minimum days per week data
is now in supplementalData.xml.  This adds functionality to
the currencygen program to parse this and store it in weeks.properties.

ChangeLog:

2008-07-07  Andrew John Hughes  <[EMAIL PROTECTED]>

        * src/gnu/currencygen/Main.java:
        Output week data to weeks.properties.
        (SupplementalHandler.SupplementalHandler(PrintWriter,PrintWriter)):
        Add new print writer for weeks.properties.
        (SupplementalHandler.endElement(String,String,String)):
        Output week data.
        (SupplementalHandler.startDocument()): Add header for weeks.properties.
        (SupplementalHandler.startElement(String,String,String,Attributes)):
        Collect week data.
