+.SH SYNOPSIS
+.B stest
+.RB [ -abcdefghlpqrsuwx ]
+.RB [ -n
+.IR file ]
+.RB [ -o
+.IR file ]
+.RI [ file ...]
+.SH DESCRIPTION
+.B stest
+takes a list of files and filters by the files' properties, analogous to
+.IR test (1).
+Files which pass all tests are printed to stdout. If no files are given, stest
+reads files from stdin.
+.SH OPTIONS
+.TP
+.B \-a
+Test hidden files.
+.TP
+.B \-b
+Test that files are block specials.
+.TP
+.B \-c
+Test that files are character specials.
+.TP
+.B \-d
+Test that files are directories.
+.TP
+.B \-e
+Test that files exist.
+.TP
+.B \-f
+Test that files are regular files.
+.TP
+.B \-g
+Test that files have their set-group-ID flag set.
+.TP
