There is a LinkedIn group where this library is discussed:

At the moment the functions are not very well documented. Generating some useful functions has a higher priority. Most functions are easy to understand, but when there is a function that would benefit greatly from better documentation: let me know.
If you would like to see a certain function: let me know.
To install the library on your system run install.sh. Use ‘source /usr/local/bash/BASHInitialisation.sh’ (in .bashrc) to initialise the library. To use the scripts add /usr/local/bash/bin to your PATH.
