     This information file is located in the \SOFTWARE\UTILS directory, which 
contains software to achieve conversion of FITS headers to and from ordinary  
text files.  This will allow easy editing of the headers, which otherwise     
contain no end-of-record delimiters.  No syntax checking is performed on the  
format of the FITS header.  In addition to the FITSXTND.* and FITSUTIL.*      
files, the following files are included:                                      
                                                                              
FITS2TXT.C   - Source code for the conversion program to make text files      
               out of a standard FITS header.  It is written for              
               Borland's Turbo C, version 2.                                  
FITS2TXT.COM - Executable version of the above.                               
FITS2TXT.MAK - MAKEFILE for FITS2TXT.  It compiles the program under the      
               Tiny memory model.  This file will create an EXE file,         
               which you may then convert to a COM file using EXE2BIN.        
               This will give a smaller (and faster) program.                 
TXT2FITS.C   - Source code for the conversion program to make a standard      
               FITS header out of a text file.                                
TXT2FITS.COM - Executable version of the above.                               
TXT2FITS.MAK - MAKEFILE for TXT2FITS.  It compiles the program under the      
               Tiny memory model.  This file will create an EXE file,         
               which you may then convert to a COM file using EXE2BIN.        
               This will give a smaller (and faster) program.                 
TEST.HDR     - A sample FITS header (an EXTENSION header, in this case),      
               which may be used to test the above programs.                  
UTILINFO.TXT - This file.                                                     
                                                                              
                                                                              
The programs may either take their inputs from the command line or            
interactively, as shown below:

          Asks for the name of the FITS header file.  Creates an output       
          file with the extension .TXT.
