<title>Description</title>
<para>
The <command>opensc-explorer</command> utility can be
used to perform miscellaneous operations
such as exploring the contents of or sending arbitrary
APDU commands to a smart card or similar security token.
</para>
<para>
If a <replaceable class="parameter">SCRIPT</replaceable> is given,
<command>opensc-explorer</command> runs in non-interactive mode,
reading the commands from <replaceable class="parameter">SCRIPT</replaceable>,
one command per line.
If no script is given, <command>opensc-explorer</command>
runs in interactive mode, reading commands from standard input.
</para>
