Inspired by Ravi Ramkissoon's fetchyahoo utility.
[http://fetchyahoo.sourceforge.net/]
and by  Vadim Zeitlin's yahoo2mbox utility.
[http://www.lpthe.jussieu.fr/~zeitlin/yahoo2mbox.html]

The basic mechanism for logging on to Yahoo has been taken from fetchyahoo and
email address unmangling has been taken from yahoo2mbox.

Needs atleast one parameter : the group to be downloaded.
You can also provide the begin and end message id to download.

If you dont want to keep a message yet skip its download make it a zero byte file

The program will create a directory in the current directory for every group
it downloads. Each message id will be a separate file in that folder.

By default the tool will run in verbose mode assuming the user wants to run it
in batch mode. Set a environment variable VERBOSE to a false value to run in
quite mode.

[DOS/Windows Only] Run the script prefixing "perl -T" since ActivePerl doesnt seem
to know how to do it automatically. In any case the script will complain if you
dont do so.

To get a MBOX formated file run the mboxify.pl script with parameters Folder name and
destination mbox File Name

The script will by default restart the download process and by default will remember
who you logged in as when you retrived the last set of messages

If you are directly connected to the internet set the following environment variable
PERL_LWP_USE_HTTP_10=1


# Mandatory : group to download
# Optional : begining message id and ending message id.

------------------------

To run : yahoo2maildir.pl <group name> [<begin message id> [<end message id>]]

Quite mode : 
env VERBOSE=0 yahoo2maildir.pl <group name> [<begin message id> [<end message id>]]

Quite mode with unicode support turned off : 
env VERBOSE=0 LANG=en_US yahoo2maildir.pl <group name> [<begin message id> [<end message id>]]
