 -f[file]         list    : lfile name  MUST have this.
  
 -dfile           file    : d-file containing list of sites to plot
  
 -df              file    : file contains the names of unwanted sites. 
 -delete_file     file    : file contains the names of unwanted sites. 
  
 -lat[latitude]   min max : vertical scale. If not issued it will be approx calculated.
  
 -long[longitude] min max : horizontal scale.  If not issued it will be approx calculated.
  
 -proj1            value   : Macator projection scale in inches per degree at equator (inches:xxxx), where xxxx is input [0.0255 default]
  
 -proj2            value value : Winkel triple projection, central meridian, minor half axis in inches  [default 0 2.0]
  
 -proj3            value value : Stereographic Equal Area, long centre, lat centre, radius (inches), latitude of radius  [default 0 90 4 60]
  
 -frame           value   : gmt border frame  ticks. [Default is  10 degrees].  
  
 -anot            value   : gmt border label intervals. [Default is  20 degrees].  
  
 -title           text    : Add a title to the top of the plot  
  
 -portrait                : include this command if you want to make portrait plot
  
 -font           value    : font size of station names [Default is 7]  
  
 -cal                     : Use this for california plots as faults/folds and better coastline will be plotted 
  
 -turk                    : Use this for turkey plots as faults/folds and better coastline will be plotted 
  
 -skip                    : skip making new plot files and plot old ones 
  
 -bold           file     : file containing names of sites to print in bold 
  
 -names          file     : file containing sites to print with names and symbols 
  
 -star       lat lon      : latitude and longitude of a red star to plot 
  
 -color                   : make a color plot 
  
 -coast_res               : coastline resolution (f,h,i,l,c) full,high,inter,low,crude [default=i] 
  
 -min_area                : minimum area of features to be plotted km^2 [default = 200]
  
 -linear                  : DO not plot linear scale.
 -linearxp                : Default is lower right corner. Linear distance scale longitude position
 -linearyp                : Default is lower right corner. Linear distance scale lattitude positio
 
   Note:   If specialized maps are used (-cal or -turk options), the location of the maps on
           your system must be set as 'root_map'.  The default is '~/gg/maps' where 'gg' is 
           an alias in your home directory pointing to the level above 'gamit' and 'kf'.
