I have published minor updates to the Lorem-Ipsum and Concat packages for NodeJS. You can get the updates through NPM. An issue in Lorem-Ipsum that saw 'undefined' appear in program output has been closed. An issue in Concat in which files could be included multiple times under certain circumstances has also been closed.
To install the latest version of Lorem-Ipsum (0.0.9):
npm install lorem-ipsum -g
To install the latest version of Concat (0.2.4):
npm install concat -g
Note that you can install both of these packages locally in your projects and require them as well. They are however, most useful as command line utilities and so benefit from doing a global install.
