   In order to run Ptolemy, two things are necessary:
      1.  Create a user called "ptolemy" (no quotes). 
      2.  Set certain environment variables correctly.  The following 
          script, appearing in the .cshrc file of ~ptolemy, will set
	  the appropriate values.
------------------------------------------------------------------------------
#/bin/csh
if ( ! $?PTOLEMY ) then
    setenv PTOLEMY ~ptolemy
endif

if ( ! $?OCTTOOLS ) then
    setenv OCTTOOLS ~ptolemy/octtools
endif

if ( ! $?ARCH ) then
    setenv ARCH snake
endif

set path=(. $PTOLEMY/bin.$ARCH $PTOLEMY/bin $PTOLEMY/octtools/bin.$ARCH $path)

# if ( ! $?USER ) then setenv USER bush endif

# if ( ! $?DISPLAY ) then setenv DISPLAY tereza:0.0 endif
