+.TH IPADDRCHECK "1" "June 2013" "ipaddrcheck 0.1" "User Commands"
+.SH NAME
+ipaddrcheck \- an IPv4 and IPv6 validator suitable for use in scripts
+.SH SYNOPSIS
+.B ipaddrcheck
+\fI<OPTIONS> \fR[\fISTRING\fR]
+.SH DESCRIPTION
+ipaddrcheck is capable of checking various facts about IPv4 and IPv6 addresses,
+from checking whether the address is valid to checking whether it is an IPv4
+multicast address, host or network address and many more.
+.SH OPTIONS
+If more than one option is given, they work as logical AND (i.e. if one of them
+fails, overall check result is fail). Logical consistency of the options is
+left up to the user. The program does not detect whether given options are
+compatible, so a mutually exclusive combination like "--is-ipv4 --is-ipv6"
+will be accepted and simply return fail for any argument.
