NAME
	xfinverse - forms the inverse of a list of transformations

SYNOPSIS
	xfinverse

DESCRIPTION
  XFINVERSE will take the inverse of each transformation in a file.
  The only option is whether to set the translations to zero or retain
  them in the output.  The latter would give the true inverse, but the
  former has been useful in arcane realignment procedures.
  
  Inputs to the program:
  
  Input file with list of transformations
  
  Output file for inverse transformations
  
  0 to set the translations (shifts) to zero, or one to retain them
  and output the true inverse transformation
