349a9ea25fSXin LI.Nm
359a9ea25fSXin LIis a filter that allows the viewing of files compressed with Lempel-Ziv

549a9ea25fSXin LIWhen multiple files are specified,
559a9ea25fSXin LI.Nm
569a9ea25fSXin LIwill pause at the end of each file and present the following prompt to the user:

599a9ea25fSXin LI.Ed

619a9ea25fSXin LIWhere
629a9ea25fSXin LI.Sy prev_file
639a9ea25fSXin LIis the file that was just displayed and
649a9ea25fSXin LI.Sy next_file
659a9ea25fSXin LIis the next file to be displayed.
669a9ea25fSXin LIThe following keys are recognized at the prompt:

789a9ea25fSXin LIIn this mode
799a9ea25fSXin LI.Nm
809a9ea25fSXin LIwill assume
819a9ea25fSXin LI.Xr gzip 1
829a9ea25fSXin LIstyle compression since there is no suffix on which to make a decision.
