+.SH NAME
+jailcheck \- Simple utility program to test running sandboxes
+.SH SYNOPSIS
+sudo jailcheck [OPTIONS] [directory]
+.SH DESCRIPTION
+jailcheck attaches itself to all sandboxes started by the user and performs some basic tests
+on the sandbox filesystem:
+.TP
+\fB1. Virtual directories
+jailcheck extracts a list with the main virtual directories installed by the sandbox.
+These directories are build by firejail at startup using --private* and --whitelist commands.
+.TP
+\fB2. Noexec test
+jailcheck inserts executable programs in /home/username, /tmp, and /var/tmp directories
+and tries to run them from inside the sandbox, thus testing if the directory is executable or not.
+.TP
+\fB3. Read access test
+jailcheck creates test files in the directories specified by the user and tries to read
+them from inside the sandbox.
+.TP
+\fB4. AppArmor test
+.TP
+\fB5. Seccomp test
+.TP
+\fB6. Networking test
+.TP
+The program is started as root using sudo.
+
+.SH OPTIONS
+.TP
+\fB\-\-debug
+Print debug messages.
+.TP
+\fB\-?\fR, \fB\-\-help\fR
+Print options and exit.
+.TP
+\fB\-\-version

+.TP
+\fB[directory]
+One or more directories in user home to test for read access. ~/.ssh and ~/.gnupg are tested by default.
+
+.SH OUTPUT
+For each sandbox detected we print the following line:
+
+        PID:USER:Sandbox Name:Command
+
+It is followed by relevant sandbox information, such as the virtual directories and various warnings.
