.SH DESCRIPTION
Zdiff compares two files ("\-" means standard input), and if they
differ, shows the differences line by line. If any given file is
-compressed, its uncompressed content is used. Zdiff is a front end to
+compressed, its decompressed content is used. Zdiff is a front end to
the diff program and has the limitation that messages from diff refer to
temporary filenames instead of those specified.
