  LIMITATIONS : cannot be run in the background....  It takes less than a minute....
              : one job in the current  directory at a time
              : don not clean tmp* files while  running.
  
  
  example:
  
   sh_delaunay -f vslr -t t  slr -cs 1.e6 -wm 5.e6 -color -d BAYO-SEUR-SIPD  CINE-KASO-SOKE KALE-KARS-PATN 
  
 -f[ile]         file  : input GLOBK getrel-file 
  
 -wm            ##     : Size of rotation wedges. Default is 5.e6.
 -wedge_mag
  
 -ws            ##     : Rotation scale. Default is .25 
 -wedge_scale
  
 -cs            ##     : Strain scale. Default is 2.e6. 
 -cross_scale           
  
                         
 -cal                  : CALIFORNIA fault files. turns off Turkey plot.
                         
 -exclude              : do not use Turkey plotter. In future, this will be default.
                         
 -t[ype]  selection    : plotting area characteristics
               type selections 
                        turk_all  turk_marmara turk_west turk_east  turk_eq eq_co eq_post turk_central turk_west_half      
  
 -c[omment]   text    : No need for quotes. This option should be issued LAST 
  
 -put    directory     : copies psfile to directory. Default is /p1data1/thesis/oral/FT_vel. 
  
 -net                 : DO not plot network.
  
 -corner              : DO not plot triangle corners.
  
 -name                : Write site names. DEfault is no.
  
  -filter             : Do not filter anything. [-cut -epssig  do not apply]. Default is filter.
                      : When filter is on FYI file: fort.30 into which  everything is dumped. 
  
 -cut        angle    : maximum uncertainty in the  axes of principla strains. Default is 45 degrees. [FIltered < 90].
  
 -epssig              : strain uncertainties. [ -cut angle applies]
                        DEfault. Do NOT plots strains if corresponding sigmas exceed the values.
                        Allows plotting  strains if  strains  are less than max-sigma 
                                   Useful if  only one component is resolved.
                        
 -scale      [1,2,3.92,4.894]    : scale the uncertainties in getrel file. Default is 2. NO other scales are coded.
                        
 -epssigplot          :  Plot   strain sigma offset by theta sigma. Default is OFF.
                        
 -concat               : Enable later concatenation of several psfiles by removing end-of-file marks.
                       : You cannot print this file.
  
  ============== OPTIONAL file selections:  =================================================================
  
 -strfile        name : Strain file from delaunay output. No headers.
  
 -rotfile        name : Rotation file from delaunay output. No headers. 
  
 -delaunayfile   name : Your very own delaunay output. No headers.
  
 -networkfile    name : Your very  delaunay newtwork. No headers.
  
  ============== OPTIONAL GMT  selections:  =================================================================
  
 -h[eader]             : TURN OFF header prints. Good for thesis plots. Default is ON, print header.
  
 -JGMTparameters       : projection size.  Default is	  -Jm.25     (mercator) Refer to GMT manual 
  
 -RGMTparameters       : projection range. Default is  -R22/48/32/45 (mercator) Refer to GMT manual
