Hi Guys,
I am trying to reading in comma seperated values in awk. I can set the delimiter to be a comma, but the tricky part is that commas that appear within quotes are not to be considered as delimiters. Could someone please help.

appconfig::args
AppConfig::Args(3pm) User Contributed Perl Documentation AppConfig::Args(3pm)
NAME
AppConfig::Args - Perl5 module for reading command line arguments.
SYNOPSIS
use AppConfig::Args;
my $state = AppConfig::State->new(\%cfg);
my $cfgargs = AppConfig::Args->new($state);
$cfgargs->parse(@args); # read args
OVERVIEW
AppConfig::Args is a Perl5 module which reads command line arguments and uses the options therein to update variable values in an
AppConfig::State object.
AppConfig::File is distributed as part of the AppConfig bundle.
DESCRIPTION
USING THE AppConfig::Args MODULE
To import and use the AppConfig::Args module the following line should appear in your Perl script:
use AppConfig::Args;
AppConfig::Args is used automatically if you use the AppConfig module and create an AppConfig::Args object through the parse() method.
AppConfig::File is implemented using object-oriented methods. A new AppConfig::Args object is created and initialised using the new()
method. This returns a reference to a new AppConfig::File object. A reference to an AppConfig::State object should be passed in as the
first parameter:
my $state = AppConfig::State->new();
my $cfgargs = AppConfig::Args->new($state);
This will create and return a reference to a new AppConfig::Args object.
PARSING COMMAND LINE ARGUMENTS
The "parse()" method is used to read a list of command line arguments and update the STATE accordingly. A reference to the list of
arguments should be passed in.
$cfgargs->parse(@ARGV);
If the method is called without a reference to an argument list then it will examine and manipulate @ARGV.
If the PEDANTIC option is turned off in the AppConfig::State object, any parsing errors (invalid variables, unvalidated values, etc) will
generate warnings, but not cause the method to return. Having processed all arguments, the method will return 1 if processed without
warning or 0 if one or more warnings were raised. When the PEDANTIC option is turned on, the method generates a warning and immediately
returns a value of 0 as soon as it encounters any parsing error.
The method continues parsing arguments until it detects the first one that does not start with a leading dash, '-'. Arguments that
constitute values for other options are not examined in this way.
FUTURE DEVELOPMENT
This module was developed to provide backwards compatibility (to some degree) with the preceeding App::Config module. The argument parsing
it provides is basic but offers a quick and efficient solution for those times when simple option handling is all that is required.
If you require more flexibility in parsing command line arguments, then you should consider using the AppConfig::Getopt module. This is
loaded and used automatically by calling the AppConfig getopt() method.
The AppConfig::Getopt module provides considerably extended functionality over the AppConfig::Args module by delegating out the task of
argument parsing to Johan Vromans' Getopt::Long module. For advanced command-line parsing, this module (either Getopt::Long by itself, or
in conjunction with AppConfig::Getopt) is highly recommended.
