SYNOPSIS

 PERL PROGRAM NAME: iTop_Mute2_config.pl 
 AUTHOR: Juan Lorenzo
 DATE: July 27 2016 
 DESCRIPTION Combines configuration variables
     both from a simple text file and from
     from additional packages.

 USED FOR 
      Upper-level variable
      definitions in iTop_Mute3 
      Seismic data is assumed currently to be in
      su format.

 BASED ON:
 Version 1  Based on linux command "cat"
 Version 2 based on Sucat.pm June 29 2016
    Added a simple configuration file readable 
    and writable using Config::Simple (CPAN)
     
   
 Needs: Simple (ASCII) local configuration 
      file is iTop_Mute3.config

  Package control:
     filename is file, without a suffix!
     In some cases, numbers must be
     separated by commasi-- needed by 
     Seismic Unix

Notes from bash

anonymous array reference $CFG

 contains all the configuration variables in
 perl script

     file_name                  = '30Hz_All_geom_geom';
     gather_header      = 'fldr';
     offset_type                = 'tracl';
     first_gather       = 1;
     gather_inc                 = 1;
     last_gather        = 100;
     freq                   = '0,3,100,200';
     gather_type        = 'fldr';
     min_amplitude      = .0;
     max_amplitude      = .75;
