##
## Initialization.  This reads and parses STDIN.
##
##  Usage:  ParseStdin::initStdin();
##
sub initStdin
{
  while (<STDIN>) {
    chomp;
    my ($name, $value) = split /=/,$_,2;
    %parameters->{$name} = $value;
  }
};

##
## Determine whether the parameter exists.
##
## Usage: print "hello" unless (ParseStdin::hasParameter("foobar"));
##
sub hasParameter
{
  my $name = shift;
  return (exists (%parameters->{$name}));
}


##
## Get the value of the parameter.
## You may optionally pass a default value as the second parameter to
## the function.
##
## Usage: print ParseStdin::getParameter("foo", "bar");
##
sub getParameter
{
  my $name = shift;
  if (exists (%parameters->{$name})) {
    return (%parameters->{$name});
  } else {
    return shift;
  }
}
