NAME

XAS::Lib::Modules::Environment - The base environment for the XAS environment

SYNOPSIS

Your program can use this module in the following fashion:

 use XAS::Class
   version => '0.01',
   base    => 'XAS::Base',
 ;

  $pidfile = $self->env->pid_file;
  $logfile = $self->env->log_file;

  printf("The XAS root is %s\n", $self->env->root);
