0. Summary
   
   I've added several features to Plotmtv1.4.1 to 
   enhance graphic outputs (both X and PS).  
   Now, it has more variety of colormaps and
   alternative PS fonts.


1. Installation

   Step 1 :
     Tar off original "Plotmtv1.4.1.tar.gz" ( or "Plotmtv1.4.1.tar.Z" )
     to build source tree.
   
     gunzip -c Plotmtv1.4.1.tar.gz | tar xvf -

   Step 2 :
     Tar off "mtvpatch.tar.gz" ( or "mtvpatch.tgz" ) to
     write several new files and overwrite some files to
     the same directory trees. This file should be tarred off
     at the same position as "Plotmtv1.4.1.tar.gz" because
     both have the same tree structure. 

     gunzip -c mtvpatch.tar.gz | tar xvf - 

   Step 3 :
     Follow plotmtv's installation procedure. Then, all set.

2. Controlling outputs
