+.SH NAME
+zdiff \- decompress and compare two files line by line
+.SH SYNOPSIS
+.B zdiff
+[\fI\,options\/\fR] \fI\,file1 \/\fR[\fI\,file2\/\fR]
+.SH DESCRIPTION
+zdiff compares two files and, if they differ, writes to standard output the
+differences line by line. A hyphen '\-' used as a file argument means standard
+input. If any file given is compressed, its decompressed content is used.
+zdiff is a front end to the program diff and has the limitation that messages
+from diff refer to temporary file names instead of those specified.
+.PP
+\&'zdiff \fB\-v\fR \fB\-V\fR' prints the version of the diff program used.
+.PP
+The formats supported are bzip2, gzip, lzip, xz, and zstd.
+.PP
+zdiff compares file1 to file2. The standard input is used only if file1 or
+file2 refers to standard input. If file2 is omitted zdiff tries to compare
+file1 with the corresponding uncompressed file (if file1 is compressed), and
+then with the corresponding compressed files of the remaining formats until
+one is found.
+.PP
+Exit status is 0 if inputs are identical, 1 if different, 2 if trouble.
+Some options only work if the diff program used supports them.
