An index for a MySQL CLOB column cannot be created with Liquibase createIndex at the moment, 
since MySQL requires a length limit for this index, see http://dev.mysql.com/doc/refman/5.5/en/create-index.html

As a workaround, you can use the modifySql to 'fix' the sql generated like so:
<createIndex tableName="foo" indexName="i_foo">
    <column name="myClobColumn"/>
</createIndex>
<modifySql dbms="mysql">
    <replace replace="myClobColumn" with="myClobColumn(80)"/>
</modifySql>

import java.io.IOException;

/**
 * Class that copies stdin to stdout, as compained about as not being cleanly
 * writable in Java on Hacker News.
 * In real code, you would just write IOUtils.copy(System.in, System.out),
 * which does basically the same thing.
 * This does not catch any exceptions as a) this is just an "exercise" and
 * b) all we could do with them is pretty-print them. So let the runtime 
 * print them for you.
