		CRU: Convert, Compress, and Restore File Utility
	 
	 
	    This program is primarily designed for operations on text files,
	and includes the following options:
	 
	    1) Converts files between fixed and variable length records.
	    2) Converts carriage control types (FORTRAN, LIST, and NONE).
	    3) Converts between 8 column tabs and spaces.
	    4) Truncates or padds records.
	    5) Removes trailing blanks and tabs from records.
	    6) Selects a range of pages for output.
	    7) Compresses (or restores) records.
	 
	    The compression algorithm is based on repeat characters, and is
	therefore especially effective on reducing the storage required for
	files which contain significant amounts of filler (spaces) or nulls.
	    The program was written in MACRO-11 and uses large buffers for
	efficient processing.
