+.TH ZFORCE 1
+.SH NAME
+zforce \- force a '.gz' extension on all gzip files
+.SH SYNOPSIS
+.B zforce
+[ name ...  ]
+.SH DESCRIPTION
+.I  zforce
+forces a .gz extension on all
+.I gzip
+files so that
+.I gzip
+will not compress them twice.
+This can be useful for files with names truncated after a file transfer.
+On systems with a 14 char limitation on file names, the original name
+is truncated to make room for the .gz suffix. For example,
+12345678901234 is renamed to 12345678901.gz. A file name such as foo.tgz
+is left intact.
