=head1 NAME

Finance::Quote::IndiaMutual  - Obtain Indian mutual fund prices from amfiindia.com

=head1 SYNOPSIS

    use Finance::Quote;

    $q = Finance::Quote->new;

    %stockinfo = $q->fetch("indiamutual", "amfiindia-code"); # Can
failover to other methods
    %stockinfo = $q->fetch("amfiindia", "amfiindia-code"); # Use this
module only.

    # NOTE: currently no failover methods exist for indiamutual

=head1 DESCRIPTION

This module obtains information about Indian Mutual Fund prices from the
Association of Mutual Funds India website amfiindia.com.
The information source "indiamutual" can be used
if the source of prices is irrelevant, and "amfiindia" if you
specifically want to use information downloaded from amfiindia.com.

=head1 AMFIINDIA-CODE/ISIN

In India, not all funds have an ISIN. However, they do have a scheme code.
You can use those if you can't find the ISIN. See AMFI site for details.
http://www.amfiindia.com/nav-history-download

=head1 LABELS RETURNED

Information available from amfiindia may include the following labels:

method link source name currency nav rprice sprice.  The link
label will be a url location for the NAV list table for all funds.

=head1 NOTES

AMFI provides a link to download a text file containing all the
NAVs. This file is mirrored in a local file /tmp/amfinavlist.txt. The local
mirror serves only as a cache and can be safely removed.
