+zstdgrep(1) -- print lines matching a pattern in zstandard-compressed files
+============================================================================
+
+SYNOPSIS
+--------
+
+`zgrep` [*grep-flags*] [--] _pattern_ [_files_ ...]
+
+
+DESCRIPTION
+-----------
+`zgrep` runs `grep (1)` on files or stdin, if no files argument is given, after decompressing them with `zstdcat (1)`.
+
+The grep-flags and pattern arguments are passed on to `grep (1)`.  If an `-e` flag is found in the `grep-flags`, `zgrep` will not look for a pattern argument.
+
+EXIT STATUS
+-----------
+In case of missing arguments or missing pattern, 1 will be returned, otherwise 0.
