+.TH ZCMP "1" "November 2010" "Zcmp (zutils) 0.8" "User Commands"
+.SH NAME
+Zcmp \- decompress and compare two files byte by byte
+.SH SYNOPSIS
+.B zcmp
+[\fIoptions\fR] \fIfile1 \fR[\fIfile2\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 uncompressed content is used. Compressed files are uncompressed on
+the fly; no temporary files are created.
+The supported compressors are bzip2, gzip, lzip and xz.
+.PP
+Compares <file1> to <file2>. If <file2> is omitted zcmp tries the
+following:
+If <file1> is compressed, compares <file1> to the file with the
+corresponding decompressed file name (removes the extension from
+<file1>).
+If <file1> is not compressed, compares <file1> to the uncompressed
+contents of <file1>.[bz2|gz|lz|xz] (the first one that is found).
+If no suitable file is found, compares <file1> to data read from
+standard input.
+.PP
+Exit status is 0 if inputs are identical, 1 if different, 2 if trouble.
