<term>Text output format with empty meta info (<option>-e</option>)</term>
<listitem>
<para>
The input strings are terminated with '\n', and may not contain '\0',
'\0xff' or '\n' characters. This is the default.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>Text output format (<option>-t</option>)</term>
<listitem>
<para>
Lines are terminated with '\n', input string and meta info are
separated by '\t'. Input and meta strings may not contain '\0',
'\0xff', '\n' or '\t' characters. A terminating '\0' (if found) is
removed from the end of the meta info.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>Text output format with numerical info (<option>-n</option>)</term>
<listitem>
<para>
Lines are terminated with '\n', input string and meta info are
separated by '\t'. Input strings may not contain '\0', '\0xff', '\n'
or '\t' characters. Meta strings are unsigned integers ([0-9]+), which
will be are retrieved from the binary representation in the
automaton. Valid data sizes are 1, 2 or 4 bytes, for sizes other than
these only the first 2 or 4 bytes are used.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>Binary output format, with base64 encoded meta info (<option>-b</option>)</term>
<listitem>
<para>
Both the input string and meta info are terminated by '\0'. The input
string must not contain the reserved characters '\0' and '\0xff'. The
meta info is base64 encoded, as it may contain any character.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>Binary output format with raw meta info (<option>-B</option>)</term>
<listitem>
<para>
Both the input string and meta info are terminated by '\0'. The input
string must not contain the reserved characters '\0' and '\0xff'. The
meta info must not contain '\0'.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>Text output format, with the perfect hash value instead of meta
info (<option>-p</option>)</term>
<listitem>
<para>
The format is the same as for text output with numerical info, but the
perfect hash value for each string is used instead of meta info.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>Dot output format for visualization using GraphViz (<option>-d</option>)</term>
<listitem>
<para>
Output a dot format graph, with the start and final states marked and
edges labeled with transition symbols. The <command>dot</command> tool
can be used to generate graphical output (e.g. PostScript) of the
graph. Use this format for small automata only (a few hundred states
or less), as the graph soon becomes quite complex.
