FITSUTIL is a special purpose utility C program which manipulates             
FITS files. MicroSoft compiler version 5.1 and large model memory             
is used.  The  main menu displays the options provided. Each of               
these  options  calls a module to  perform  the  required  task.              
Please note that this is used for the Comet Giacobini-Zinner test             
disk files where the 2880 byte stream of FITS header or data is               
preserved.                                                                    
Following is the list of modules and their specific tasks:                    
                                                                              
 FITSUTIL.C   contains the menu of options.                                   
 MAKEHDR.C    creates only a *.HDR file(no CR-LF's) using a *.FIT file.       
 MAKEHDCR.C   creates only a *.TXT file(has CR-LF's) using a *.FIT file.      
 TXT2HDR.C    creates a *.HDR(no CR-LF's) file using A *.TXT(CR-LF's) file.   
 MKHDIMIB.C   creates *.HDR and *.IMG or *.IBG files using a *.FIT file.      
 MKHDTBDA.C   creates *.HDR and *.TAB or *.DAT files using a *.FIT file.      
 MKHDRIMQ.C   creates *.HDR and *.IMQ files from a *.FIT file.                
 IMIB2FIT.C   creates a *.FIT file using *.HDR and *.IMG or *.IBG files.      
 TBDA2FIT.C   creates a *.FIT file using *.HDR and *.TAB or *.DAT files.      
 IMQ2FIT.C    creates a *.FIT file using *.HDR and *.IMQ files.               
                                                                              
As an example, to create *.hdr and *.imq files using a *.fit file, option     
corresponding to MKHDRIMQ above must be selected or to split a *.fit file     
into *.hdr and *.dat files, one must select MKHDTBDA module.
