+.TH ZCMP "1" "January 2019" "zcmp (zutils) 1.8" "User Commands"
+.SH NAME
+zcmp \- decompress and compare two files byte by byte
+.SH SYNOPSIS
+.B zcmp
+[\fI\,options\/\fR] \fI\,file1 \/\fR[\fI\,file2\/\fR]
+.SH DESCRIPTION
+Zcmp compares two files ('\-' means standard input), and if they differ,
+tells the first byte and line number where they differ. Bytes and lines
+are numbered starting with 1. If any given file is compressed, its
+decompressed content is used. Compressed files are decompressed on the
+fly; no temporary files are created.
+.PP
+The formats supported are bzip2, gzip, lzip and xz.
+.PP
+Zcmp compares file1 to file2. If file2 is omitted zcmp tries the
+following:
+.IP
+1. If file1 is compressed, compares its decompressed contents with
+the corresponding uncompressed file (the name of file1 with the
+extension removed).
+.IP
+2. If file1 is uncompressed, compares it with the decompressed
+contents of file1.[lz|bz2|gz|xz] (the first one that is found).
+.IP
+3. If no suitable file is found, compares file1 with data read from
+standard input.
+.PP
+Exit status is 0 if inputs are identical, 1 if different, 2 if trouble.
